Design Features

The NTX-20 controller is an economical solution for feeder automation where Ethernet and/or serial connectivity is desired. Combining both Ethernet and serial connectivity, master gateway, IED gateway, router, internal GPS precision time reference interface, binary inputs, and power supply functions in a single–package module, the NTX-20 controller interfaces with distribution line switches, capacitor banks, transformers, distributed substation breaker bays, water pumps, valve control devices, etc., to provide low–cost automation with the highest reliability possible. Deployed on a per–device basis, the NTX-20 with optional control output modules adds control and data acquisition to a power distribution system for one or more feeder line switches, auto– regulator transformers, and capacitor banks.NTX-20 controllerUsing this switch control and our optional D 060 Intelligent Analog Input Module, your distribu- tion automation system can plot alternate distribution paths around faulty circuits to restore service automatically, using our fault detection, isolation and restoration (FDIR) application from a centralized master, or with the CentrixTM Advanced Feeder Automation platform (our substa- tion island-based feeder platform). Trouble–spot displays at the control center to give operators precise location information aid in manually dispatching service personnel. The result is shorter service interruptions, affecting smaller areas.


The NTX-20 provides a low cost data acquisition and control solution for both power distribution and water and gas applications. Local closed–loop control or calculations can be easily accom- plished with the optional IEC 611131–compliant Programmable Logic Controller (PLC). The NTX-20 and all optional expansion modules are 35 mm DIN–rail compatible, for convenient mounting in cabinets or remote device enclosures.

Technical Specifications

The NTX-20 is a 35 mm DIN–rail mounted dual–PCB module. It uses an ARM 9 E 32–bit RISC processor. The peripheral set includes USB Full Speed Host and Device interfaces and a 10/100 Base T Ethernet MAC. The NTX-20 operat- ing system is Linux with flash memory. The internal GPS Satellite Receiver synchronizes the system clock with UTC time. An optional external antenna is required to receive the NMEA-0183 protocol satellite time messages. The NTX-20 network interface supports a DNP/IP and Modbus RTU/IP client, a DNP/IP and Modbus RTU/IP server, or multiples of both. Two isolated serial channels are individually configurable for master slave (secondary) or IED master (primary) Modbus RTU and DNP3 Level 3 protocol emulations with configurable baud rates of 300 to 115.2 Kbps.


The internal power supply accepts a 18–36 VDC input, with a maximum consumption of 10 watts. The NTX-20 has a 4x6 optically isolated control relay driver matrix, with a capacity of 24 control relay output drivers. External control relay modules can be supplied as momentary or latching relays with a variety of contact ratings. Relay coils are for a standard nominal 24 VDC external power source.Legacy primary (master) protocols, such as Cooper 2179, are supported. Legacy secondary (slave) protocols, such as ACS7000, L&G 8979, Harris 5000, SC1801, SComD, etc., are also supported (others may be added based on customer demand). The NTX-20 includes 16 optically isolated binary inputs that are configurable for binary with time (SOE), binary without time (simple status), Form A counter, or two consecutive points as a Form C counter. The binary inputs are scanned by a separate micro- processor at a 1–millisecond rate for a 1–millisecond event resolution. A sliding software de–bounce filter requires a changed contact to be in the same state for four consecutive millisecond scans before accept- ing a change of contact state. The binary input buffer can store up to 256 event changes between master scans. Binary input wiring connec- tions are made to a 3.81 mm removable compression terminal block that can accept up to #12 AWG (2.5mm2) wire.


An optional I/O expansion bus adds these modules:

  • Up to two 1–channel analog output modules
    (isolated 4–20 mA output) with added external power supply
  • Up to four 8–point binary input expansion modules
    (binary with or without time, Form A or two consecutive points for Form C counters)
    The NTX-20 includes a non–volatile, on–board UTC Time/Date clock, which can be synchronized via protocol or the on–board GPS satellite clock interface for precise 1ms resolution accuracy (using the optional external GPS clock/antenna).
  • Up to four 6–point DC analog input modules (0 ± 1 mA or 4–20 mA input)

Distributed Energy Resourses Management System - DERMS

 

DERMS - Distributed Energy Resources Management System

 

Interest in renewable integration within distribution networks is on the rise, both within the utility industry and with the public at large. If the legacy SCADA is not PRISM ADMS, the best value for return of investment, with the fastest time to implement, is a distributed Centrix platform that integrates seamlessly with existing SCADA system, feeder devices, communications systems and remote terminal units. The solution is to deploy a flexible architecture to manage the various components seamlessly, without expensive changes to legacy systems. The ACS Distributed Energy Resources Management System (DERMS) offers this flexibility, enabling communication between the various devices necessary to accomplish the coordinated optimization of the feeder controlling devices.

 

What can DERMS do for your grid

 

Increased renewable penetration throughout the power grid landscape is a growing trend. As renewable deployment grows, DERMS will optimize the performance of the feeder network and monitor in real time of impending problems. As renewable injection reaches critical mass, DERMS will safely maximize the amount of injection that is possible, or to provide emergency solutions to avoid network violations.

DERMS works as follows

 

PRISM DERMS issues control signals to feeder devices with the objective to optimize the operation of the feeder network. DERMS lowers the end of line Voltage and the line drop Voltage using LTC and regulators and reduces feeder losses through improvement of the power factor with capacitor switching. DERMS specific control to optimize the feeder includes dynamic control of the inverter’s real and reactive power injection from renewables such as photoVoltaic (PV) distributed energy resources and energy storage.

NTX-U57 ( TG5700 RTU and I/O Subsystem Upgrade Solution )

 


NTX-U57 Controller

The Advanced Control Systems (ACS) NTX-U57 is a cost effective and feature-rich upgrade solution for L&G/Siemens TG5700 RTU & I/O subsystems. The NTX-U57 replaces the original TG5700 Controller Card piggy-back mounted on the original Termination Card (for each I/O subsystem type other than SBO Control), eliminating the need to disturb or replace any of the existing fi eld wiring. For the utility, this means up to 60% cost savings over a traditional RTU replacement, since the work required to reproduce drawings, re-cable, and do extensive point checkout is vastly reduced. The original TG5700 Station Manager or Supervisor Module host can be replaced with a NTX series Substation Controller, or any substation system that supports DNP/IP. 

 

Features and benefits:

 

  • Powerful, open-system architecture based on ARM 9E 32–bit RISC processor and Linux OS
  • Can be integrated with the ACS NTX-200 series substation controllers as the Supervisor Module or Station Manager Controller host, or with another substation control platform
  • Plugs directly into existing termination cards - no need to touch the existing wiring
  • No changes to the existing SCADA system database are required when using the same master protocol
  • Replaces proprietary protocol between modules with DNP 3.0 – opening up the system for easy expansion
  • Dual Ethernet ports support DNP3, Modbus TCP/IP or UDP with up to 8 IP clients, servers or multiples of both; also functions as integrated 2-port integrated Ethernet switch • Large 14,000 point database capacity per module
  • Provides time synchronization via IRIG-B (un-modulated), GPS satellite clock, NTP or DNP3 protocol
  • Easily expandable by adding ACS I/O subsystems to an NTX series Supervisor Module or Station Manager Controller host, or by using ACS-produced replacement termination panels paired with additional NTX-U57 units
  • Easily confi gured using our intuitive, Windows-based NTX Explorer application
  • Achieve NERC CIP compliance with the use of built-in solutions

 

NTX-U57/D

NTXU57D
The NTX-U57/D upgrade module replaces the TG5700 Digital Input Logic module, which plugs directly into the original TG5700 termination card. All customer contact input wiring is untouched in the upgrade. Each NTX-U57/D upgrade supports 32 optically isolated Digital Inputs, confi gurable per point as: binary with time (SOE with 1mS resolution); binary without time (Status/Indication); or Form A or two consecutive-point Form C counters (Accumulators).Contact wetting voltage is the voltage supplied by the original TG5700 Termination Panel, or the 18-24 VDC Power Supply provided for the NTX-U57/D module. The NTX-U57/D Binary Input Subsystem scans the 32 inputs every millisecond. Contact bounce is fi ltered by using a configurable sliding software fi lter; a chatter fi lter may also be confi gured. Each binary input point with or without time may also be non-inverted, or inverted where useful for point state definitions.
 

NTX-U57/A

NTXU57D
The NTX-U57/A upgrade module replaces the TG5700 Analog Input Logic module and plugs directly into the original TG5700 Termination Card. All customer analog input Panel wiring is untouched in the upgrade. The NTX-U57/A supports 24 DC diff erential Analog Inputs, with scaling utilized from the existing TG5700 Termination Panel Base. The NTX-U57/A uses a fully bi-polar ± 10 VDC (+ 5 VDC scalable), 16–bit A/D converter, and the analog termination cards carry scaling resistors. With legacy master slave protocols that support only 12–bit numeric values, the NTX-200 series substation controller, or other substation system host, normally strips out the four least signifi - cant bits. All ACS emulations of legacy protocols allow you to determine which four bits of the IED-supplied 15-bits scaled into engineering units are removed, without touching the sign bit. 
 

NTX-U57/C

NTXU57D
The NTX-U57/C upgrade module for retrofit of the TG5700 combination I/O node logic module plugs directly into the original TG5700 Termination Panel. All customer digital and analog input and existing Interposing Control Relay Panel wiring are untouched in the upgrade. Each NTX-U57/C upgrade supports 8 optically isolated Digital Inputs, confi gurable per point as binary with time (SOE with 1mS resolution); binary without time (Status/ Indication); or Form A or two consecutive-point Form C counters (Accumulators). Contact wetting voltage will be the voltage supplied by the original TG5700 Termination Panel, or the 18-24 VDC Power Supply provided for the NTX-U57/C module. Six DC diff erential Analog Inputs are available, with scaling resistors utilized from the existing TG5700 Combo Node Termination Panel Base. Positive 2.5 VDC and zero analog Reference Points are also provided as the 7th and 8th analog points. A fully bi-polar ± 10 VDC (+5 VDC scalable), and a full 16-bit A/D converter is utilized. The NTX-U57/C upgrade module provides 4 on-board Trip/ Close Relay output pairs that are expandable, using up to 28 T/C external interposing control relay pairs. The NTXU57/ C supports assigning T/C contact momentary relay closure times, in 1-millisecond increments, for each relay via the DNP3 TCP/IP or UDP protocol network interface to an NTX-U57/C control interface.
 

NTX-U57/R

NTXU57D
The NTX-U57/R replacement in the ACS upgrade incorporates a Binary Output Controller with an RS485 serial interface to any NTX-U57 upgrade panel’s unused second TG5700 RS485 conductor. ACS or customer-supplied isolated 24 VDC power supply will provide each module with 24 VDC power that will utilize the original TG5700 daisychained power conductors. The existing TG5700 Control Relay Panel is removed and the ribbon cables are simply moved from the TG5700 Relay Output Controller to the 26-pin cable connectors on the NTX-U57/R replacement. The NTX-U57/R provides an optically isolated, high-current 8 x 8 driver matrix for addressing each group of 4 T/C (or Latch/Reset) relays on up to 8 TG5700 Control Relay Modules, for a maximum of 32 relay pairs per NTX-U57/R. The original addressing jumpers are re-used as binary addresses 0 through 15 to select which U57/R Controller is being addressed by the master. Up to 16 NTX-U57/R Relay Controllers can be supported with a maximum of 1024 relays per upgraded TG5700 system.
 

Replacement Boards

NTXU57D
ACS has also developed replacement TG5700 Analog, Digital and Combo Node termination boards. These replacement Termination boards can be purchased with our NTX-U57 upgrade I/O subassembly modules to expand an existing TG5700 I/O confi guration, or separately in case of a TG5700 Termination board failure. These modules are not intended to work with original TG5700 Logic boards, but with ACS Upgrade Logic boards only.
