Description

technical field [0001] The invention relates to the field of power system simulation, in particular to an ADPSS-based SVC controller closed-loop detection platform and a self-defined modeling method. Background technique [0002] With the development of power system, the stability of power system has become the main concern of people. In order to improve the power transmission capacity of the power system, the voltage stability is generally improved by installing a static dynamic reactive power compensation device SVC. SVC is generally composed of TCR and filter branches of each harmonic. By controlling the opening angle of the thyristor in the TCR, the impedance characteristics are changed, and adjustable inductive reactive power is provided. Capacitance of different capacities is provided by controlling the switches of each filter branch. sexual reactive power. Especially with the continuous construction of the UHV power grid, the charging power of the UHV AC transmissio...

Problems solved by technology

Compared with the closed-loop test based on the dynamic simulation laboratory, this modeling and test method is simpler and more flexible. For example, the closed-loop test platform of the SVC device was established based on the Canadian RTDS (Real Time Digital Simulator, real-time digital simulation device), but The platform is limited by simulation nodes and simulation scale, and the scale of the power grid that can be simulated is small, which cannot meet the needs of SVC dynamic performance testing under the interconnected large power grid.
