摘要
已有的各种数学模型不能解释±20MvarSTATCOM装置在实际运行中其稳态输出电流和控制角δ之间较强的非线性关系。为此,文章具体分析了STATCOM装置各种损耗的特点,利用输入输出建模法和能量方程,建立了STATCOM装置的输入输出非线性数学模型。将±20MvarSTATCOM装置实测参数代入所建模型中得出的仿真结果与现场实验结果一致表明所建STATCOM非线性数学模型的正确性。该数学模型对大容量STATCOM装置动态行为分析及控制系统设计具有较大的参考价值。
The nonlinear relationship between the steady output current and control angle δ of a ±20 Mvar static compensator (STATCOM) can not be adequately explained by existing mathematical models. The losses in a ±20 Mvar STATCOM were analyzed to develop an Inout nonlinear mathematical model of a STATCOM using inout modeling and energy equations. The simulation results agree well with field test results. The model can accurately analyze the dynamic performance of a STATCOM and can be used to design STATCOM control strategies.
