由于在实时数字仿真器(RTDS)上通过增加RACK数目来加大系统仿真规模的成本过高,一种可行的方法是对系统末端交流电网进行机电暂态仿真,系统主干交直流电网利用RTDS进行电磁暂态实时仿真,即实现基于RTDS的电磁-机电暂态混合实时仿真.为此,文中在RTDS的CBuilder开发环境下,开发实现了CBuilder自定义机电暂态仿真模块,并与RTDS电磁暂态仿真模型成功对接.通过采用CBuilder下的多线程技术和高斯网络化简技术,有效提高了RTDS上的机电暂态仿真计算规模.利用IEEE标准数据验证了所开发的机电暂态自定义模块的正确性,并在基于RTDS的电磁-机电混合仿真中成功加以应用,通过与全电磁模型的对比,证明了基于RTDS的混合仿真的有效性.

As the cost of increasing RACKs of the real-time digital simulator (RTDS) to enlarge the scale of system simulation is too high, a feasible method is proposed to simulate the marginal AC power grid with the electromechanical transient simulation method, while the AC-DC main grid is simulated with the electromagnetic transient method for RTDS, that is, the realization of the hybrid real-time simulation of power system electromechanical transient and electromagnetic transient process based on RTDS. To this end, the user-defined simulation module of electromechanical transients based on CBuilder is realized,and the module is successfully connected with RTDS electromagnetic transient models. By adopting the technology of multithreading and Gauss network reduction, the computing scale of electromechanical transients simulation is improved. The validity of the electromechanical transients simulation module programmed by CBulider language is proved by IEEE standard data. The module has been successfully applied in the hybrid simulation of electromechanical transient and electromagnetic transient based on RTDS. The hybrid simulation results are validated by comparing with those of all electromagnetic models.This work is supported by National Mega-projects of Science Research for the 11th Five-year Plan (No. 2006BAA02A17)and National Natural Science Foundation of China (No. 50807014).
