| 摘 要： | 为满足现代电力系统实时仿真的发展需求，提出一种基于可编程电源的数模动模混合仿真系统。利用动模实验室搭建动模仿真系统，并在RTDS中搭建39节点系统作为数字仿真系统模型，结合以理想变压器模型算法作为功率接口算法的接口系统，形成一个800 V/345 kV的动模数模混合实时仿真系统实验平台。在研究混合仿真接口两端系统延时对系统稳定性和准确性影响基础上，提出用二阶相位超前环节对下发通道和上传通道的接口延时进行相位补偿，以提高系统稳定性和准确性。通过对所搭建的数模动模混合仿真系统的实验，并与纯数字仿真进行对比分析，进一步验证了混合仿真系统的有效性。

| Abstract: | To meet the development needs of modern power system simulation, a digital and dynamic analog hybrid real-time simulation system based on programmable power supply is proposed. A dynamic simulation laboratory is used to build the dynamic simulation subsystem model, and the New England 39-node system is built in RTDS as the digital simulation subsystem. Combined with an interface subsystem using the ideal transformer model as the power interface method, an 800 V/345 kV digital and dynamic analog hybrid real-time simulation system experimental platform is formed. Based on the study of the influence of system delay at both ends of hybrid simulation interface on system stability and accuracy, a second-order phase advance link is proposed to compensate for the interface delay of the transmitting channel and the uploading channel, and a power interface subsystem is proposed to improve system stability and accuracy. Through an experiment of the dynamic analog and hybrid simulation system, and by comparison with pure digital simulation, the effectiveness of the hybrid simulation system is further verified.
