Modeling of a Static VAR Compensator* Q/ e% D3 P5 H
The Static VAR Compensator (SVC) component is based on state variable modeling techniques. It is primarily composed of a thyristor controlled reactor (TCR) and a thyristor switched capacitor (TSC). A state variable formulation solves the differential equations of the system for capacitor voltages and inductor currents. The dependence of the system matrices on the value of the time step is directly proportional, and thus the time step can be readily changed during a run as it is required for the switching elements to be modeled adequately. The Static VAR Compensator model Interfaces to EMTDC as a Norton current source. 3 W$ L* m/ j. x1 A/ N3 h8 y8 d: p, g" P& s( ^7 T: O
The general circuit diagram of the SVC simulated by the Static VAR Compensator component is shown below. All elements shown in this figure are incorporated into the model, and their dynamic behavior is mathematically described within the model by a set of state variable equations. # j7 l4 z; R; A0 M $ s$ T& n- ~4 V/ @# C4 V" Y8 z说的是SVC的模型是用“公式”描述的吗?还是我理解有偏差,请前辈们指导
