摘要: 准确的宽频带阻抗测量是发现和解决未来双高电力系统稳定性问题的重要基础,但直接向电力系统注入谐波进行测量可能会带来失稳的风险,而基于半实物仿真技术可以以较低的成本与风险实现较为准确的宽频带阻抗测量。实时仿真器的计算性能和仿真规模取决于目标计算机的计算能力,仿真精度与规模顾此失彼,难以兼顾,并且随着电力系统仿真规模要求的不断提高,单一的实时仿真系统越来越难以满足大规模仿真的要求。使用多个实时仿真器协同进行联合仿真,是提高仿真规模的有效途径。首先构建了基于CloudPSS-RT和RT-Lab联合实时仿真平台的在线阻抗分析装置,并通过构建光伏与双馈风力发电系统,验证了在线阻抗分析装置的准确性和有效性。

Abstract: High penetration of renewable energy in power grid challenges power system operation and stability evaluation, due to the fast dynamic behaviors of power electronic devices. The accurate broadband impedance measurement is one of the critical aspects of power system stability analysis. The impedance measurement method of injecting harmonics to the actual power system may bring the risk of instability. The hardware-in-the-loop simulation technology can achieve accurate broadband impedance measurement with lower cost and risk. The computing accuracy and simulation scale of real-time simulators depend on the computing power of the target computer. As the demands of large-scale power system increase, a single real-time simulation system may not meet the requirements. Co-simulation between multiple real-time simulators is an effective way to increase the scale of the simulation. This paper proposed an online impedance analysis co-simulation framework based on the CloudPSS-RT and RT-Lab platform and verified the accuracy and effectiveness of the co-simulation by constructing a PV and DFIG power generation system.
