晶闸管型互联装置多时间尺度转换等效模型
Equivalent Model of the Thyristor-Type Inter-Connector for Multi-Time Scale Transform
摘要
Abstract
Flexible interconnection of power grids draws more and more attention. The novel inter-connector based on thyristor-controlled zigzag transformer can be applied to the interconnection of synchronous power grids, closed-loop operation of distribution networks, flexibly opening electromagnetic loop, etc. The Thevenin equivalent model of its primary circuit with large time-scale is developed and the self-tuned interpolation algorithm is adopted, guaranteeing the simulation accuracy with relatively large simulating step. Simulation models based on devices and equivalent model are both developed for multi-timescale transform. The effectiveness of the flexible interconnector as well as correctness of the equivalent model is validated. Simulations are implemented by the steps of 50μs and 300μs, respectively, using the two kinds of models. It is demonstrated that the proposed equivalent model shows satisfied accuracy under both steps. The simulation time consumptions are around 14.5%and 10.3% of the device-based simulation model, approving a sharply decreased computation.关键词
