电力系统中的电源规划和静态无功补偿规划已经形成了相对成熟的理论和方法,但对于动态无功补偿的规划研究则尚未起步。利用 PSCAD/EMTDC软件,从动态无功需求分析和补偿容量选择原则两个方面进行仿真分析,研究感应电动机动态无功负荷的需求特性;给定负荷水平下不同的负荷模型和参数对负荷动态无功需求的影响;电网强弱和负荷模型对母线暂态电压稳定的影响。验证了依据动态无功需求测算来配置动态无功补偿装置补偿容量的可行性,并提出相应的规划方法。
電力繫統中的電源規劃和靜態無功補償規劃已經形成瞭相對成熟的理論和方法,但對于動態無功補償的規劃研究則尚未起步。利用 PSCAD/EMTDC軟件,從動態無功需求分析和補償容量選擇原則兩箇方麵進行倣真分析,研究感應電動機動態無功負荷的需求特性;給定負荷水平下不同的負荷模型和參數對負荷動態無功需求的影響;電網彊弱和負荷模型對母線暫態電壓穩定的影響。驗證瞭依據動態無功需求測算來配置動態無功補償裝置補償容量的可行性,併提齣相應的規劃方法。

There are comparatively mature theories and methods for power source planning and static var compensation plan-ning in power system but planning for dynamic reactive power compensation has not started up. By using PSCAD/EMTDC software and in aspects of analysis on dynamic reactive power demand and selection principle of compensation capacity,sim-ulation analysis was conducted for studying demand characteristics of dynamic reactive power load of the motor,impact on load dynamic reactive power demand by different load models and parameters with given load level and impact on transient voltage stability of the bus by strongness and weakness of the power grid and load models. Feasibility of deploying dynamic reactive power compensation device according to dynamic reactive power demand was verified and relevant planning methods were proposed.
