摘要
本文通过采用电力系统分析综合程序(PSASP),以某工矿企业电网为例,通过建立系统的数学模型,选择适合实际情况的扰动变量,应用该软件对电网的频率动态过程进行了仿真分析.分析结果表明,有功功率等参数的改变会对电网频率动态响应产生不同的影响效果.此项工作对研究工矿企业电网频率的动态特性响应,以及采取相关有效措施,遏制频率崩溃,保证系统安全稳定运行,提供了有力的分析依据.
In order to analyze the frequency dynamic characteristics of the industrial and mining enterprises power grid,the power system analysis program（PSASP） is introduced in this paper.Take some of a industrial and mining enterprises power grid for example,the grid dynamic process simulation analysis has been done through establishing a mathematical model and choosing the suitable actual disturbance variables using this software.The analysis results show that with the active power and other parameters changing the frequency dynamic response of the power system will has different effects.This work has provided a theoretical basis to the frequency dynamic characteristics of the industrial and mining enterprises power grid,which can ensure the safe and stable operation of the system by taking relevant effective measures and preventing frequency collapse.
