Simulation modeling method for static var compensator
2013
The invention discloses a simulation modeling method for a static var compensator (SVC). The static var compensator comprises a group of thyristor control reactors and at least one group of filter capacitors, wherein each filter capacitor is formed by connecting a resistor, an inductor and a capacitor in series. The simulation modeling method comprises the following steps: building a main circuit model and a general controller model in simulation software, wherein a main circuit parameter calculator is designed in the main circuit model; inputting the capacitance and bus voltage of the static var compensator; calculating inductance parameters of thyristor controlled reactors and distributing the capacities of the filter capacitors of all groups by the main circuit parameter calculator; calculating to determine parameters of the capacitors, the inductors and the resistors in the filter capacitors of all the groups by the main circuit parameter calculator. According to the simulation modeling method, the trouble that main circuit parameters are required to be redesigned when system simulation personnel change the capacity of the SVC each time can be avoided, and the better convenience is brought to flexible configuration of the static var compensator at each node of a power grid by the system simulation personnel for system simulation research.
