提出一种基于实时仿真系统的地区电网自动电压控制(automatic voltage control,AVC)系统闭环检测方法。基于该方法建立了地区电网AVC系统检测平台,该平台由实时仿真系统、中间数据转换接口装置、地区电网AVC系统3部分组成。在实时仿真系统中构建的系统模型包含系统平台模型和中央控制系统模型,通过中间数据转换接口装置将实时仿真系统的模拟量和开关量转换后传给地区电网AVC系统,由AVC系统计算得到控制策略后再通过中间数据转换装置回传到实时仿真系统。该闭环检测平台解决了地区电网AVC系统在现场测试的难题,实现了地区电网AVC系统在试验室检测的目标。
A closed-loop detection method of automatic voltage control (AVC) system for regional power network based on real-time simulation system is proposed. Based on this method, the regional power grid AVC system detection platform is established. The platform consists of real-time simulation system, intermediate data conversion interface device and regional power grid AVC system. The system model built in the real-time simulation system includes the system platform model and the central control system model. Through the intermediate data conversion interface device, the simulation quantity and switch quantity of the real-time simulation system are converted and transmitted to the regional grid AVC system, which is calculated and controlled by the AVC system Strategy and then through the intermediate data conversion device back to the real-time simulation system. The closed-loop detection platform solves the problem of field power network AVC system testing in the field and realizes the goal of regional power network AVC system testing in the laboratory.
