含风电虚拟惯性响应的电力系统等效惯性时间常数计算
|
摘要
文章研究了含风电虚拟惯性响应的电力系统等效惯量定量计算方法,探究了风电虚拟惯性响应对电力系统惯性耦合特征的定量影响规律。在计算单个风电场等效虚拟惯性时间常数基础上,考虑不同风电渗透率情况,给出了电力系统等效惯性时间常数解析计算表达式,通过仿真算例对电力系统等效惯性时间常数的解析结果进行验证,并分析了电力系统等效惯量的时变特性。
The quantitative calculation method of equivalent inertia in power system with virtual inertia response of wind power and the quantitative influence law of wind power virtual inertial response to power system inertia coupling characteristics are studied in this paper. Firstly, the equivalent virtual inertial time constant of a single wind farm is calculated. Next, analytic expression of equivalent inertial time constant in power system is obtained according to different penetrations of wind power.Then the time-varying characteristics of the equivalent inertia are analyzed. Finally, simulations verify our results.
