摘要:
 富水电地区电网，水电、风电等新能源电源众多，电网低频振荡特性复杂。针对这一情况研究了电网低频振荡影响机理，包括电网结构和运行方式对电力系统动态稳定水平的关联性。另外，通过菲利普[CD*2/3]海富隆模型推导出机组参数对系统振荡阻尼影响机理，并提出了基于粒子群人工智能算法的富水电地区电网PSS参数优化方法。以恩施电网为例，仿真验证了采用新方法对恩施地区水电机组PSS参数进行优化后，可显著抑制低频振荡风险。
Abstract:
 There are many new energy sources in rich hydropower area, such as hydropower, wind power and so on, and the low frequency oscillation characteristics of power grid are complex. This paper studies the influence mechanism of low frequency oscillation, including the correlation between power network structure and operation mode on the dynamic stability level of power system. Furthermore, the influence mechanism on system oscillation damping is deduced by Phillips-Heffron model, and the optimization method of power grid PSS parameters based on PSO is proposed. Based on the example of Enshi Power Grid, the PSS parameters of the hydropower units in Enshi area are optimized by the method proposed in this paper, which has remarkable effect on suppressing the risk of low frequency oscillation.
