摘　　要：为了及时、准确地监测变电站变压器的真实运行状态,考虑分布式电源接入,文中提出了变电站油浸式变压器运行状态监测方法。将变电站油浸式变压器状态监测数据分为同步信号和报头信息两部分,同步信号的默认长度为12个符号长度,通过微控制器将变电站油浸式变压器状态数据传输至多个跳频频道上,并根据不同变电站油浸式变压器的频率,自动调整通信速率、输出功率和带宽参数,实现油浸式变压器的状态监测。通过测试结果表明,设计方法输出的信号频率与变压器的额定频率一致,具有较好的监测效果。In order to timely and accurately monitor the true operating status of substation transformers,considering the integration of distributed power sources,this paper proposes a method for monitoring the operating status of oil immersed transformers in substations.The status monitoring data of oil immersed transformers in substations is divided into two parts:synchronization signal and header information.The default length of the synchronization signal is 12 symbols.The status data of oil immersed transformers in substations is transmitted to multiple frequency hopping channels through a microcontroller,and the communication rate,output power,and bandwidth parameters are automatically adjusted according to the frequency of different oil immersed transformers in substations to achieve status monitoring of oil immersed transformers.The test results show that the signal frequency output by the design method is consistent with the rated frequency of the transformer,and has good monitoring effect.
