Timing Parameter

This application can define the following timing parameters:

• The duration between program iterators, at which time the program will
  calculate and correct the power factors.
• How oftern commands will be retransmitted to the Load Control Relays.

Drag & Drop Interface

 This Application provides drag and drop interface for defining:

• Billing Points
• Feeders
• Capacitor Breaks
• Line Sections
• Connectivity

Custom WorldView Screen   

This application allows users to create a custom WorldView interface screen to initiate control, set limits, display all power factor point data and much more. This provides benefits like:

• Reduce Losses
• Reduce Power Factor Penalties
• Correct & Maintain Power Factor at the Billing Point Level
• Correct & Maintain Power Factor at Feeder Level
• Define retransmission intervals for one-way communication Load Control Relays

2-Part Architecture

The goal of this 2-part architecture is to provide:

• You implement your choice of supervisory logic using command sequencing, calculations, or any mechanism that will provide the appropriate values in the database points used to control the executive program.
• Ready-to-use functionality at the executive level, where the details follow a standardized algorithm to reduce, maintain or restore the voltage.

Voltage Reduction

•  The subject voltages in your system are controlled by voltage regulators or tap changers that are represented by controllable points in the SCADA system. Regulators to be considered for control are additionally represented
  by Voltage Regulators defined in the voltage reduction database.
• Voltage regulators are organized into one or more groups. All voltage reduction decisions are made on a per-group basis. For this reason, all regulators in a group should be operating at the same “nominal” voltage (although their actual measured voltages will of course vary).
• Typically, a supervisory command sequence will determine when it wants to reduce voltage for one or more of the groups, based on conditions in the power system. The command sequence sets the values of database points that instruct the executive program to reduce or restore the voltage for the desired groups.
• The voltage reduction executive program reacts to each group’s input point by issuing controls to the appropriate database points to manually decrease or increase the position of the voltage regulator.

Voltage Regulation   

Each voltage regulator is represented within SCADA by a collection of database points, including:

• A controllable point to put the regulator into Automatic or Manual mode (only in Manual mode will the regulator be manipulated by the Voltage Reduction program)
• A controllable point to Raise or Lower the regulator step by stepAn analog point to indicate the regulator's current position number
• An analog point containing the measured voltage being controlled by that regulator
