【摘要】 基于电网部分电压相量和电流相量可测的条件下 ,推导出了整个电网电压相量的线性状态估计表达式 ,并对测量随机误差对电压相量状态估计的影响进行了分析。由于对电网电压相量的状态估计是线性的 ,因此能实时实现对电网的监视。更多还原

【Abstract】 This paper presents the linear expression of the state estimation of voltage phasor for the whole power network based on the fact thatpartof the bus voltage phasor and current phasor being measurable.The effects of the stochastic errors of measured phasor on the state estimation of voltage phasor are analyzed.The real-time monitoring to the power network can be realized with the linear state estimation of voltage phasor.更多还原
