摘要

首先，通过实时数字仿真器（RTDS）的小步长模型和大步长模型构建了100 kW光伏并网发电系统仿真测试平台，包括光伏逆变器、控制器及外接电力系统等。然后，着重介绍了电流控制器的工作原理和RTDS建模方法。最后，基于该平台设计并完成了验证电流控制器控制性能的稳态、暂态仿真实验；同时，对一台实际大功率光伏并网逆变器进行了相同的现场检测试验。通过两种实验结果的对比分析，证明了基于RTDS的大功率光伏并网发电系统测试平台的有效性，说明了其具备在模拟实际工况下对控制器进行研究、分析的能力且可行性较强，具有一定借鉴意义。

Abstract

Firstly

a 100 kW grid-connected photovoltaic (PV) power generation system simulation platform including PV inverter

controller and external power system is established by real-time digital simulator (RTDS) big-step models and small-step models. Then

the current controller’s working principle and its RTDS modeling method are described at length. Finally

steady state and transient simulation experiments are designed based on the platform to verify the performance of the current controller

and the same field experiment is carried out for an actual high-power PV grid connected inverter. By the contrast analysis

it is shown that the platform accustomed to the real situation is suitable for analyzing the controllers’ performance.
