介绍了中国电力科学研究院自主研发的电力系统全数字实时仿真装置(advanced digital power system simulator,ADPSS)与直流输电控制保护装置的闭环仿真试验的基本原理、硬件组成和物理接口,并重点阐述了ADPSS与物理装置联合仿真时如何保证数字仿真过程的实时性以及与物理过程同步的解决方法。ADPSS实时仿真的电力系统规模可达1000台机、10000条母线,通过ADPSS与直流输电控制保护装置的闭环仿真,可全面考察装置控制保护策略与大电网动态特性的相互作用,提高对控制保护装置的检测试验水平。

The basic principle, hardware composition and physical interfaces of closed-loop simulation of advanced digital power system simulator （ADPSS） independently developed by China Electric Power Research Institute （CEPRI） and HVDC control and protection devices are presented, and how to ensure the real-time performance of digital simulation process during the co-simulation of ADPSS and physical devices as well as the solution of synchronization with physical process are emphatically expounded. The power system simulated by ADPSS in real-time can have the scale of ten thousand buses and one thousand generators, thus through the closed-loop simulation of ADPSS and HVDC control and protection devices the interaction between the control and protection strategies of the devices and dynamic characteristics of large power grid can be comprehensively investigated, and the detection and test level of control and protection devices can be improved.
