发电厂电气主系统培训仿真实用模型

Practical Method of Training Simulation for Power Plant Electrical System

针对发电厂电气主系统培训仿真的建模问题，介绍了把发电机的一次调频特性作为分配因子的动态潮流方法．它很好地反映了由于有功扰动引起的系统频率变化特性．在考虑发电机的励磁调节特性的问题上对不同的励磁调节装置提出了相应的建模方法．给出了一种发电机饱和特性的解析算法，用以计算发电机的励磁电流．在一个实际的１２５０ＭＷ容量发电机组的大型发电厂电气培训仿真系统中，验证了这些方法的有效性．

This paper involves the model of training simulation for power plant electrical system. The dynamic load flow of power frequency nature is introduced.It depicts really the power frequency nature for real power changing. The models related to different field regulation devices are proposed.It applies to calculate the field current of the generator. An analytical method considering the saturation nature of the generator is established. The above mentioned method is successfully implemented in a 1 250 MW installed capacity power plant training simulation system.
