The paper describes the concept of synchrophasors and the introduction of synchrophasors for protection applications in IEEE PC37.118.1 and then discusses different substation and transmission line protection applications. Requirements for reporting rate, time synchronization and communications architecture are discussed. Testing of protection systems based on PMUs is described at the end of the paper.
Testing of Phasor Measurement Units (PMU devices) is necessary for any PMU application, be it a simple visualization and archiving system or a more complex set of real-time system operations tools. PMUs are available from virtually every manufacturer of protection and monitoring equipment. They are often implemented as embedded functions within relays or disturbance recorders. This paper describes...
This paper presents collected events to demonstrate the use of synchrophasor data to update and improve system models and system operation. Examples are given of responses to events captured using wide-area synchrophasor measurements. Phase angle, frequency, and voltage responses are displayed with discussion of the events, synchrophasor data views, and insights to be gained from the different data...
A dispatch-oriented risk perception and fault disposal decision support technique for online monitoring and control is proposed in this paper. It helps to improve the sensitivity and accuracy of risk perception by multi-source information mining based on data from SCADA, relay, WAMS and other measurement systems. And it provides a direct means to grasp the whole process of incident handling by online...
