基于配电网状态估计及可靠性分析

电力系统状态估计是当电网模型给定,并且知道电网设备的停运实况,根据数据采集系统采集到的实时量测数据,剔除测量数据中含有的不良数据后估计出母线的电压幅值和相角的最优值,并计算出线路或变压器上流过的有功功率和无功功率,从而对整个系统的准稳态运行情况形成完整准确的掌握。随着电力系统的负荷成为人们日益增长的生活一部分,人们对电力依赖性越来越强,所以配电网状态评估及稳定可靠性研究越为越必要性。

The state estimation of power system is based on the real-time measurement data collected by data acquisition systemwhen the grid model is given and the outage of power network equipment is known. After eliminating the bad data contained in themeasured data, the voltage amplitude and phase angle of the bus are estimated, and the active power and reactive power flowingthrough the line or transformer are calculated. In order to form a complete and accurate grasp of the quasi-steady-state operation ofthe whole system. As the load of power system becomes more and more obvious, people are more and more dependent on power, soit is more and more necessary to study the state evaluation and stability reliability of distribution network.
