链式STATCOM的高效电磁暂态仿真模型
Efficient Electromagnetic Transient Simulation Model for Cascade STATCOM
摘要
Abstract
Aiming at a problem of very slow simulation speed of the cascade static synchronous compensator (STATCOM) with cascaded multi-level structure in electromagnetic transient simulation environment such as M ATLAB and PSCAD/EM TDC, this paper proposes a kind of efficient electromagnetic transient simulation model for cascade STATCOM based on Dommel equivalent calculation principle.It makes use of Thevenin theorem to replace the bridge arm branches by controlled voltage source and numerical calculation modules, and introduces characteristics of ideal sw itching devices to reduce computation quantity.This model preserves inner transient characteristics of submodules and interface w ith the control system, w hich has features of w ide adaptability, high precision and obvious acceleration effect.It uses PSCAD/EM TDC softw are to make simulation on the proposed model under different w orking conditions to verify effectiveness and precision of the model.关键词
