摘要
提出一种应用延拓法求解以风电场注入有功功率、无功功率及传输线路导纳为分岔参数的Hopf分岔点和两参数Hopf分岔边界方法,分析了风电系统参数对电压稳定性的影响及静止无功补偿器对Hopf分岔的控制作用.仿真实验结果表明,无功功率是系统发生Hopf分岔的主要参数,静止无功补偿器可有效延迟Hopf分岔.
Based on the continuation method, active power and reactive power inputted by wind power and the admittance of wind power generation system were taken as bifurcation parameters, Hopf bifurcation points and two-parameter Hopf bifurcation boundary were calculated to analyze the influences of the system parameters on the voltage stability of wind power generation system. Meanwhile, the control action of static vat compensation on Hopf bifurcation was researched. Research result shows that reactive power is a main Hopf bifurcation parameter, and Hopf bifurcation can be effectively delayed by static var compensation.
