摘要
高压短距离 35kV馈电传输系统 ,是最常用的短距离电力系统之一 .按照物理设备对系统进行分块 ,对系统传输线模块用集总参数模型、同步发电机、变压器、综合负载分别作为独立模块建模 ,各模块的连接处用解耦电压源替代 ,这样就可对各模块平行地进行数字积分 .在已知同步发电机与综合负载模型的基础上 ,建立了馈电系统非全相运行数字仿真的数学模型 ,同时给出了相应的数字积分方法 .在奔腾Ⅲ计算机上的运行结果表明 ,所提出的模型和选用的数字积分方法是正确的 ,并且能实时实现 .
The high voltage short distance 35 kV feeding transmission system is one of the common short distance power systems . According to the physical equipment, the author takes to partitioning the system. The transmission module is used as a lumped parameter model, synchronous generator, transformer, composite load are separately operated as independent built-modules. Every module connection is substituted by a decoupled voltage source. So every module can take parallel integration. A mathematics model of feed power system non-three phase running is developed on the basis of known model of synchronous machine and composite load .The digital integration method is also given .The results of a digital example simulation running on Pentium III show that the presented model and the given digital integration method are correct and can be realized in real-time.
