| 风力发电具有波动性和间歇性,且分散接入配电网系统,势必影响并网系统电压稳定性.首先从静态电压稳定性角度出发,采用PV曲线潮流分析法,根据风电并网系统潮流计算,推导出基于潮流解存在的静态电压判据L以及基于考虑综合参数的电压—有功灵敏度的静态电压稳定裕度Kp；然后,研究提出了风电并网系统静态电压稳定充分必要条件,给出了风电并网系统静态电压稳定性流程框图与判别步骤；最后,实验验证了风电并网系统静态电压稳定充分必要条件的正确性.在此基础上,提出了改善风电并网系统静态电压稳定性的措施. |

| Wind power has the characteristics of fluctuation and intermittence and is dispersed into the distribution system,which inevitably affects the voltage stability of Wind Power Integrated Power Systems.Firstly,this paper uses PV flow analysis method from the point of view of static voltage stability,according to calculation method of power flow for Wind Power Integrated Power Systems,to deduce the Static Voltage Criterion (L) of Power Flow Calculation and the static voltage stability margin (Kp) based on voltage active-power sensitivity index.Then,it develops the necessary and sufficient conditions for Wind Power Integrated Power Systems,and gives flow chart of judging static voltage stability;Finally,the correctness of the necessary and sufficient conditions for static voltage stability of Wind Power Integrated Power Systems is verified by experiments.And the measures to improve the static voltage stability of Wind Power Integrated Power Systems are put forward. |
