无功补偿性能影响与整定方法

Performance of Reactive Power Compensation and Its Tuning Methods

在进行大功率电力电子系统的研制过程中,在没有排除中断延时、接口、计算速度等问题的前提下进行实物实验存在一定的风险。以异步发电机无功补偿技术为例提出HIL和RCP相结合的准实时仿真系统结构,并且给出了HIL和RCP两种准实时仿真时钟处理和参数整定方法。通过进行离线仿真、HIL和RCP准实时仿真,验证了参数整定方法的有效性和两种准实时仿真的可靠性。结果表明,采用该参数整定方法进行的准实时仿真能够有效的模拟实物实验,较为全面地对系统进行测试。

In the process of conducting research and high-power electronic systems, there is a certain risk for physical experiments without the information of interrupt latency, interface and computing speed. In this paper, taking asynchronous generator reactive power compensation technology for an example, quasi-real-time simulation system architecture combines HIL and RCP was proposed and two quasi-real-time simulation clock processing and pa- rameter tuning methods were presented. The validity and reliability of parameter tuning methods were verified through off-line simulation, HIL and RCP quasi-real-time simulation. The results show that the presented parameter tuning methods for quasi-real-time simulation can effectively simulate physical experiments and test the system all-sidedly.
