摘要：

静止同步无功补偿器能提供灵活可靠的无功支持，是现代电力系统的重要元件。静止同步无功补偿器由大量可关断电力电子开关组成，需要进行小时间尺度的仿真，小时间尺度仿真带来了仿真速度的大幅降低，是实时仿真的巨大挑战。为了满足同步无功补偿器的仿真需要，提升小时间尺度仿真的仿真速度，实现实时仿真功能，研究了静止同步无功补偿器的小时间尺度实时仿真系统。小时间尺度仿真系统是基于场效应可编程逻辑阵列（field programmable gate array，FPGA）的专用型电力电子设备仿真器，其由核心计算、元件区、大小步长接口和通讯等核心模块组成，具备实时仿真能力。研究了静止同步无功补偿器的小时间尺度实时仿真方法，采用两电平换流器结构和双环电流控制模型，并研究模型在小时间尺度仿真的实现方法，提出了适用于电力电子设备仿真的小步长开关模型，最后展示了静止同步无功补偿的小时间尺度仿真系统的实验结果。

Abstract:

Static synchronous compensator （STATCOM） is the important component of modern power system due to its capability of flexible reactive power support. However, small time-step simulation is required for STATCOM, because it consists of a great amount of power electronics switches. The small time-step simulation causes a substantial reduction in the simulation speed, which is the great challenge of real-time simulation. In order to meet the simulation requirements of synchronous compensator, improve the speed of small time-step simulation and realize the real-time simulation functions, this paper studied the small time-step real-time simulation system of STATCOM. The small time-step simulator is the special power electronic equipment simulator based on FPGA （field programmable gate array）, which consists of core computation block, element block, interfaces of small and large time-step networks, commutation block and other core modules, to ensure the real-time simulation. The small time-step real-time simulation method of STATCOM was studied with using two-level convertor and double loop current control model. Then, the implementation of the model in the small time-step simulator was studied, and the small-step switch model was proposed for power electronic device simulation. Finally, the experimental results of small time-step real-time simulation system of STATCOM were presented.
