摘要: |
统一潮流控制器(UPFC)集成了多种控制策略可以顺序完成多种运行工况,而多个控制策略间的平滑切换,对UPFC系统的稳定运行非常重要。提出了一种适用于多个控制策略间平滑切换的触发控制逻辑,结合各控制策略的“软切换”逻辑,实现了UPFC多个控制策略间的平滑切换,确保输电系统的稳定运行。在RTDS平台上搭建了统一潮流控制器仿真系统,设计了UPFC系统不同控制策略间平滑切换的仿真算例,对所提出的控制逻辑进行验证。试验结果表明所提出的控制逻辑是有效可行的。 |

Abstract: |
Unified Power Flow Controller (UPFC) integrates a variety of control strategies, which can complete multiple operating conditions in sequence, and the smooth switching between multiple control strategies is important for the stable operation of UPFC. A trigger control logic suitable for free switching between multiple control strategies is proposed, which can realize the smooth handoff between UPFC multiple control strategies and ensure the stable operation of power transmission system combined with the soft switching logic of each control strategy. The simulation system of UPFC is built on the RTDS platform, and simulation tests of smooth switching between different control strategies of UPFC system are designed for testing the proposed control logic. The experimental results show that the improved control algorithm is effective and feasible. This work is supported by National Natural Science Foundation of China (No. 51467003). |
