摘　　要：电力系统在通信过程中存在大量分散布置的电阻、电容,使得实际通信会出现不同振荡频率,造成通信报文无法全部获取。对此,研究分布式不停电合解环装置高可靠性通信技术。计算电力系统振荡频率,分析分布式不停电合解环装置相应频率响应特性。通过合解环前稳态电流和环路叠加,获取电流限制表达式。在电流保护定值整定条件下,设置滑动窗口,获取通信链路定位时间和报文传输故障定位时间。将传感器本地测量值转换为二进制格式,保护感知数据传输的完整性。实验结果表明,该技术通信频率波动图与实际通信频率切换波动图完全一致,且能够将980 bit数据完全传输,具有高效通信效果。In the communication process of the power system,there are a large number of scattered resistors and capacitors,which cause different oscillation frequencies in actual communication,resulting in the inability to obtain all communication messages.In this regard,research on high reliability communication technology for distributed uninterrupted power supply closed loop device.Calculate the oscillation frequency of the power system and analyze the corresponding frequency response characteristics of the distributed uninterrupted power supply closed loop device.Obtain the expression for current limitation by combining the steady⁃state current before the loop and the loop superposition.Under the condition of setting the current protection value,set a sliding window to obtain the communication link positioning time and message transmission fault positioning time.Convert the local measurement values of the sensor to binary format to protect the integrity of perception data transmission.The experimental results show that the communication frequency fluctuation diagram of this technology is completely consistent with the actual communication frequency switching fluctuation diagram,and it can fully transmit 980 bit data,with an efficient communication effect.
