为有效监测变电站设备的实时温度,提出一种基于光电振荡器的高精度温度实时监测系统。首先,将温度信息映射到光电振荡器的振荡频率;然后利用现场可编程逻辑门阵列对温度参量进行实时解算,并通过4G模块将数据无线传输至终端,完成变电站设备温度的在线监测。通过实验验证了本系统对变电站设备温度实时监测的可行性和有效性。

To effectively monitor the temperature of substation equipment in real-time,a high-precision real-time tem-perature monitoring system based on optoelectronic oscillator(OEO)was proposed in this paper.First,the temperature information is mapped into the oscillation frequency of OEO.Second,real-time processing of temperature parameters was performed by a field programmable gate array,and the temperature data was wirelessly transmitted to the terminal through a 4G module,enabling online monitoring of the substation equipment temperature.The applicability and effec-tiveness of the designed system used in real-time monitoring of substation equipment temperature was verified by experi-mental results.
