摘　　要：随着AVR装置入网检测工作深入开展,原基于控制电压(Uc)闭环方式的AVR数字物理混合仿真测试方法存在诸多限制。基于此,在RTDS中搭建了包含励磁变、可控硅整流桥和励磁绕组回路的励磁系统,并采用AVR装置输出的触发脉冲数字信号代替控制电压模拟信号Uc与RTDS系统形成闭环控制。新AVR入网检测系统更贴近现场真实工况,检测范围更广,应用场景更为丰富。实际AVR装置的检查测试结果验证所提模型与方法的有效性和优越性,更加全面检查AVR装置涉网特性。With the implementation of qutomatic voltage regulator(AVR)device testing for power grid access,the orig?inal AVR digital and physical hybrid simulation testing method based on the closed loop of control voltage(Uc)is limited in various aspects.On this basis,an excitation system with an excitation transformer,a silicon controlled rectifier and an exciting circuit was built in real time digital simulator(RTDS),and the triggering pulse digital signal output from AVR device instead of the analog signal of control voltage was used to form a close loop control with the RTDS system.This novel testing system was more in line with the real operating conditions and widely used in various scenarios.The testing results of AVR device in practice demonstrated the effectiveness and advantage of the proposed model,which can be used to test the performance related to AVR device connected to power grid more comprehensively.
