摘　　要：传统锁相控制技术对逆变器电网信号相位参数的上、下限产生严重限制作用;为解决上述问题,提出一种基于智能高压电网逆变器的新型数字化同步锁相控制技术;通过选择高压开关器件的方式,对电网数据采集电路进行完善,达到调制智能PI逆变组织的目的,完成智能高压电网逆变器的结构类型研究;在此基础上,通过确定锁相环的同步响应性能及智能控制指标,对循环的数字化控制流程进行完善,完成智能高压电网逆变器数字化同步锁相控制技术研究;对比试验结果表明,与传统技术手段相比,应用新型数字化同步锁相控制技术后,电网信号相位参数上限上升15.0×107 T左右、下限下降16.0×107 T左右。The traditional phase-locked control technology seriously limits the upper and lower limits of the phase parameters of the inverter's power grid signals.To solve the above problems,a new synchronous phase-locked control technology based on intelligent high voltage grid inverter is proposed.By selecting the high voltage switch device,the power grid data acquisition circuit is perfected to achieve the purpose of the modulation intelligent PI inverter organization,and the structure type of the intelligent high voltage grid inverter is completed.On this basis,by determining the synchronous response performance and intelligent control index of the PLL,the digital control process of the loop is perfected to complete the research of the digital synchronous phase locked control technology of the intelligent high voltage power grid inverter.The experimental results show that the upper limit of the phase parameters of the power grid signals is up to about 15×10 7T and the lower limit is about 16×10 7T,compared with the traditional technology.
