摘要:
电力系统发生故障时,系统会从一种状态变到另一种状态,并伴随产生复杂的电磁暂态现象。该文提出一种基于电磁暂态分析软件PSCAD/EMTDC环境的电动机过载仿真,利用过载运行时的数学模型代替实际电力系统,实现了数值方法对系统的运行试验和研究。该模型不仅可以对发电机故障的瞬态和稳态过程进行仿真,而且能够揭示发电机故障瞬态的运行特征及瞬态过程中各个故障量的变化规律。验证了EMTDC电动机模型和算法的有效性和正确性,为电动机故障诊断和保护的深入研究提供了有效的仿真平台。
Abstract:
When the power system fails,the system will change from one state to another, accompanied by complex electromagnetic transient phenomena.A simulation model of motor overload based on electromagnetic transient analysis software PSCAD/EMTDC is proposed.The mathematical model of overload operation is used to replace the actual power system,and the numerical method is used to test and study the operation of the system.This model can not only simulate the transient state process and the stable state process of the generator fault,and reveal the fault characteristics of generator transient operation and the change rule of each fault in the transient process.The method may greatly reduce the occurrence probability of the internal short trouble and reduce loss which caused by the grounding fault.Thus it verifies the effectiveness and correctness of the EMTDC motor model and algorithm.
