摘要
介绍了机电暂态仿真程序数值仿真法和保梯解析法的原理和计算步骤,并用上述2种方法对1000kV晋东南—南阳—荆门特高压零起升压试验中同步发电机转子电气量进行了计算和分析,得到了包括发电机侧励磁电压和励磁电流的全部电气量。计算结果表明:采用机电暂态仿真程序数值仿真法和保梯算法均可计算出特高压零起升压试验过程中发电机侧的全部电气量,计算结果误差较小,可满足工程要求;在机组参数未知的情况下,采用保梯解析法可更方便地得到特高压零起升压试验过程中发电机侧的全部电气量。
The principles and calculation procedures of numerical simulation by electromechanical transient program and Potier analytic method are described, the two methods are applied to the calculation and analysis of excitation parameters of synchronous generators during the stepping up from zero test of 1000kV AC power transmission pilot demonstration project from Southeast Shanxi via Nanyang to Jingmen, and the whole electrical parameters including the excitation voltage and current at generator side are obtained. Whole electrical parameters during the stepping up from zero test can be calculated by electromechanical transient program or Potier analytic method, the calculation results from both methods can satisfy engineering demand and their errors are allowable; whole electrical parameters at generator side during the stepping up from zero test for 1000kV AC transmission system can be more conveniently obtained by Potier analytic method while the parameters of the generation set are unknown.
