摘要: |
静止无功发生器(Static Var Generator, SVG)对故障后电力系统的动态特性具有重要作用,准确的SVG控制器参数是含电力电子设备的电力系统暂态仿真分析的关键。提出一种基于RTDS硬件在环测试的SVG控制器参数辨识方法。该方法通过搭建SVG控制器-RTDS硬件在环试验系统,将测试得到的SVG响应数据作为实测数据,对于不同的控制器参数组合,采用BPA软件进行暂态仿真,根据暂态仿真结果与实测数据的最小二乘指标进行参数辨识。通过对某实际SVG控制器的硬件在环试验验证了所提方法的正确性及有效性,能够较好地满足实际电力系统暂态仿真的应用要求。 |

Abstract: |
The Static Var Generator (SVG) plays a significant role in the dynamic characteristics of power systems after large disturbances. The accuracy of the SVG controller parameters is the key to transient simulation of power systems with power electronic equipment. This paper presents a parameter identification method for an SVG controller based on RTDS hardware-in-the-loop test. This method establishes the SVG controller-RTDS hardware-in-the-loop test system to obtain the SVG response data as the measured data. For different combinations of controller parameters, BPA software is used for transient simulation, and parameter identification is based on the Least Squares (LS) index of transient simulation results and measured results. The correctness and effectiveness of the proposed method are verified by the hardware-in-the-loop test of an actual SVG controller, which can better meet the application requirements of the actual power system transient simulation.
