电力系统中长期稳定仿真中火电机组建模的研究
|
摘要
目前电力系统稳定仿真广泛使用的汽轮机模型是IEEE1973年和1991年公布的标准模型,这些模型能反映汽轮机系统一定的特点,在多机系统仿真使用方便,但忽略了动态响应较慢的过程,不能满足中长期稳定仿真的需要。而电站仿真机使用的模型能详细反映汽轮机的特点,但微分方程太多,无法应用于多机仿真。本文使用电站仿真建模的方法,建立适用于电力系统中长期稳定仿真的汽轮机系统模型。使用Eurostag仿真软件,通过一些仿真试验,验证了所建立的汽轮机系统模型能够准确反映火电机组的动态特性,同时又满足电力系统中长期稳定仿真的要求。
At present power system stable simulation wide spread using steam turbine model is the standard model which the IEEE announced in 1973 and 1991.These models could reflect certain characteristic of the steam turbine, are easy operated in multi-machine system simulation, but could not meet mid-long term stable simulation needs. Moreover, the model used in power plant simulation machine can reflect the steam turbine characteristic in detail, but the differential equations are too many to apply multi-machine simulations. This article uses the method of the power plant simulation modelling, establishes steam turbine model that is suitable in the electrical power system the mid-term and long-term stable simulation. Using Eurostag simulation software, we made some simulation experiments to verific that the steam turbine system model can reflect power plant dynamic characteristics accurately so that can be used in power system mid-long term stable simulation.
