摘要

本文研究了一种基于状态向量控制方程和测量误差计算的状态估计方法。该方法将操作参数的限制条件作为等式和不等式加以考虑。为了考虑作为等式的限制和作为不等式的限制扰动固定，使用了一个绝对精确的测量概念，即色散等于零时的测量。该方法可以计算出考虑潮流固定、特定电站功率控制下系统频率维护、机组电压维护等因素的电力系统模式。

State estimation programs application for computation problems solution of electrical power systems steady-state modes based on operating restrictions

The state estimation method based on using control equations for state vector and measurement error computation is considered in the article. This method takes into account the restrictions on operating parameters as equalities and inequalities. To take into account the restrictions as equalities and restrictions disturbances fixation as inequalities an absolutely accurate measurement concept, i.e. the measurement when dispersion is equal to zero, is used. This method enables to calculate the electrical power systems modes considering power flows fixation, frequency maintenance in a system due to specified generating station power control, voltage maintenance in units.
