| 摘 要： | 介绍了多机电力系统分散协调励磁控制的建模方法,利用相关特性法优化计算权矩阵,在希望的系统阻尼比和适当的机端电压反馈系数的共同约束下,求解Levine-Ahlans方程组得到最优反馈系数。对一个典型复杂系统(EPRI-36系统)进行了分散控制结构约束下的全局励磁调节反馈系数优化计算。根据所得优化计算结果,使用电力系统分析综合程序(PSASP6.2)用户自定义功能对求取的励磁规律建摸、仿真。给出了Levine-Athans方程组的解和基于此解的仿真结果。

| Abstract: | This paper introduces a method of modeling coordinated excitation system based on feedback from output variables. Optimized weight matrix is obtained with the method of relativity considering the expected damp and reasonable feedback parameters of generator voltage, and the optimized feedback coefficients are got from equations of Levine-Ahlans. A typical large power system and global optimal feedback parameters for excitation regulating are computed and obtained respectively, and those variables can be measured at local units. The designed excitation laws with the optimized results are modeled and simulated by power systems analysis soft package(PSASP). Answers of Levine-Atlans equation groups and simulating results of a 8-machine 36-bus system are given. |
