摘要
本文以扩展Kalman滤波理论为基础,提出了电力负荷的非线性递推滤波(NLRF)建模法。文中首先介绍基本原理,然后将其分别应用于电力负荷的静态建模及动态建模。为了比较精确地描述负荷的动态特性,提出了新型的非线性、非机理模型。通过实际应用及数字仿真,对所提出的模型与方法进行了检验。结果表明:NLRF建模法适用范围较大,便于在线监测,滤噪性强,精度也较满意。
On the basis of extended Kalman filtering theory, a nonlinear recursive filtering (NLRF) method is proposed for the modelling of both static and dynamic characteristics of electric loads. In order to model load more accurately, a new kind of nonlinear input-output dynamic model is developed. The parameters of the model can be estimated by NLRF method according to the data recorded in field tests. The proposed model and method have been varified by practical applications and digital simulations.
