SwitchPlan

Overview

The PRISM SwitchPlan application is a tool that allows operators and engineers to intuitively create and test switching plans in advance of their implementation. These plans are saved by name and can be retrieved and manually activated at any time by an operator. They can also be initiated by a time schedule or by real–time events. The Switch Order module includes a switching plan editor that allows direct interaction with existing SCADA displays.

 

The Switch Plan Editor uses a screen–based editor that allows the user to chain together control actions in series or parallel. Selection of the Switch Plan mode from the pull–down menu allows the operator to select control devices, tags, or pseudo devices and incorporate sequence interrupts with the mouse as if they were real–time control operations.

 

 

Switch Order Manual Recording User Actions

 

 

When the switch order is in “record” mode, the control dialogue boxes display the steps in red to indicate that any action taken is recorded and automatically entered as a control action or event in the open switch plan.

 

The Switch Plan editor creates a switching order listing that can be viewed, modified and executed in a simulated or real–time mode. Each step can be replayed at a sequenced time interval, allowing the operator to watch as the displayed database points are updated as the switching order executes in test mode. Once a switch order has been created, it can be named and stored for future use. A library of switching plans can be saved. As each device is selected, a switch order editor window, shown below, is updated to reflect a listing of the operator actions. The switch plans are time tagged and archived for use, and may be copied using cut and paste to create new switch plans.

 

When all data and automatic and manual operations have been entered into the editor, they can be modified to reflect exact descriptions required for the Switch Order. Additional information may need to be added if a field crew has to find an unfamiliar location. Switching plans can be manually started and stopped by the operator, started by a time scheduler or started by a predetermined signal from the system which may indicate a distribution problem or a generation problem that requires load to be re–routed or reduced.

 

At no time will a manual or automatic switching program override an existing Control Inhibit tag. Control Inhibit tags must be removed by an operator to permit the control action.

 

 

Switch Order Input Options

 

The switching order steps can be reflected on the network map showing the location of each step on the network geographic map (if available) and schematic one-line with a designated numbered symbol identifying the step. This feature is provided to show improved visualization of the sequence of each switch plan step which involves remotely and manually operated devices identified in the database and/or model.
