Abstract

This invention disclosure introduces novel concepts related to platforms for wide-area control and protection applications. It proposes an integrated unit that provides synchrophasor data acquisition from phasor measurement units (PMUs) or other sources, time alignment based on the C37.244 protocol, execution of custom, user-defined logic in the form of functional mockup-units and communication of control signals through extensions of the C37.118 protocol to PMUs or other means of actuation. Although the applied technologies are individually known and standard, the combination is new and not documented by the prior art.

Abstract This invention disclosure introduces novel concepts related to platforms for wide-area control and protection applications. It proposes an integrated unit that provides synchrophasor data acquisition from phasor measurement units (PMUs) or other sources, time alignment based on the C37.244 protocol, execution of custom, user-defined logic in the form of functional mockup-units and communication of control signals through extensions of the C37.118 protocol to PMUs or other means of actuation.

Although the applied technologies are individually known and standard, the combination is new and not documented by the prior art.

1. Background Brief statement of how things worked before the invention

Currently synchrophasor solution for example PSGuard only provides monitoring functionality. However, several customers have requested closed loop control functionality (WAMPAC). Although most of the current applications are conceptually extendable to provide control signals to correct a detected instability (e.g., the line thermal monitoring and voltage stability monitoring detect overloads that can be alleviated by generator dispatch or load shedding), there are a number of practical problems to solve in order to add control functionality: • WAMPAC systems have challenging performance and reliability requirements. • The decision logic for actuation, e.g. load shedding, often needs to be customized. • The communication of decision logic output to remote actuators. Past implementation of WAMPAC logic has often been developed as bespoke solutions engineered from scratch based on particular project requirements. This resulted in long engineering time and custom solutions that are expensive to develop and maintain.

2. Statement of the problem Briefly explain the problem solved with the invention. If applicable explain how the competition solves the problem.

Whereas the decision logic of a WAMPAC system is typically specific to a project or application, the basic performance and reliability requirements are similar between projects. Therefore there is a need to separate the implementation of a WAMPAC system into two major parts:
