摘要

为实现含分布式电源的电力系统实时仿真，研究了一种基于实时数字仿真器(RTDS)和现场可编程门阵列(FPGA)联合仿真平台的多速率实时仿真方法。采用局部延迟插入方法分解电力系统网络，并利用拟合法和外插法实施并行多速率接口电气量交互。为减小通信延时对仿真精度的影响，提出了一种FPGA数据发送适当早于RTDS数据发送的接口电气量异步交互方法。在RTDS和FPGA联合仿真平台上以50 μs/1 μs混合仿真步长实时仿真了一个含2个光伏发电的IEEE 5节点电力系统，并与PSCAD平台下的仿真数据进行对比，验证了所提联合仿真平台的可行性和实时仿真方法的准确性。

Abstract

For the realization of real-time simulation of power system with distributed generations

this paper studies a multi-rate real-time simulation method based on the real-time digital system(RTDS)and field programmable gate array(FPGA)co-simulation platform. The power network is divided by the partial latency insertion method

and multi-rate interaction of interface electric parameters is implemented by the fitting method and the extrapolation method. In order to reduce the influence of communication delay on simulation accuracy

a method of asynchronous interaction of interface electric parameters which enables FPGA's data to be transmitted prior to RTDS's data is proposed. An IEEE-5 power system containing two photovoltaic generations is simulated in real-time on the RTDS and FPGA co-simulation platform with a 50 μs/1 μs hybrid simulation step

the result of which is compared with the simulation data of PSCAD platform

and the feasibility of the proposed co-simulation platform and accuracy of the real-time simulation method are verified. This work is supported by National Natural Science Foundation of China(No. 51477114)and Science and Technology Planning Project of Tianjin(No. 13TXSYJC40400).
