基于RTDS的风光发电系统数字物理混合仿真分析

风光发电系统的仿真分析研究是发展可再生能源发电技术的重要环节,本文针对风光发电系统数字物理混合实时数字仿真的关键技术展开研究,构建风光发电系统电气架构和通信架构,采用实时数字仿真器作为研究工具,建立基于RTDS纯软件的各微电源单体控制系统模型和基于RTDS的数字物理混合仿真单体微电源模型,并分别在稳态和动态两种情况下对其进行仿真分析,研究两者间特性的差异,证明所建模型的有效性,为两类模型的选择使用提供指导。数字物理混和仿真分析条件更接近于实际情况,既可在物理平台上对控制策略的性能进行检验和调试,又可实时修正控制参数、控制策略,为实际工程设计提供重要实践依据。

Hybrid Simulation Analysis of Wind/Photovoltaic System Based on Real-time Digital Simulator

The simulation analysis of wind/photovoltaic power generation system has become an important part of the development of renewable energy generation technologies. The critical technologies for wind/photovoltaic power generation system is studied based on real-time digital simulation, and electrical power architecture and communication architecture are built by using real-time digital simulator as a research tool. Each micro-power single control system model is built based on pure software RTDS and micro-power single physical hybrid simulation model, and simulation is analyzed in steady state and dynamic state. The differences between both properties are studied, the validity of the model is proved, and selectable guidance for two models is provided. Conditions of hybrid simulating analysis are close to the actual situation, which not only can both test and debug control strategy performance on the physical platform, but also can correct control parameters and control strategy in real-time, and it provides an important basis for the actual engineering design.
