The static var compensators (SVC) are widely used for the electrical power system and the industrial customers, while high level electromagnetic interference (EMI) produced by the semiconductor switching may cause malfunction of the SVC or unaccepted response of victim devices positioned nearby. According to the configuration of a SVC and the dynamic performance of the random load, equivalent models...
Due to frequent switching of the thyristors in a static Var compensator installed within a power substation, large amount of broadband electromagnetic emissions are being generated, which results in electromagnetic contamination to both the power grids and the victim electronic devices positioned nearby. Based on optical fiber, circuit and field transducers, an advanced acquisition system is established...
In this paper, a simulation model is established to investigate on the conducted mechanism in substations installed with SVC (Static Var Compensator) devices with a view to characterizing the main causes of the conducted interference. The high-frequency macro model for thyristors is established with a nonlinear time-varying resistor to simulate the switching characteristics of the thyristors. Based...
