【摘要】 根据±50 Mvar链式静止无功补偿器(STATCOM)的实际设计,建立其仿真模型,分析其运行原理和稳态特性,通过PSCAD仿真软件计算得到其各项稳态性能指标满足要求。在传统的STATCOM数学模型基础上,建立了考虑各种损耗的链式STATCOM详细的暂态、稳态数学模型,解释了链式STATCOM稳态运行时的若干非线性现象,利用PSCAD仿真软件对±50 MvarSTATCOM进行稳态仿真研究,验证了上述分析结果的正确性。更多还原

【Abstract】 This paper presents the operation principle of ±50 Mvar STATCOM with chain-circuit topology based on equipment design, establishes detailed mathematical models taking into account of several kinds of equipment losses. The detailed model can interpret several nonlinear phenomena of the STATCOM. By using PSCAD digital simulation software, ± 50 Mvar STATCOM is simulated under steady state conditions. The result has shown that the proposed conclusion is right.更多还原
