The invention provides a monitoring method and device for power station equipment, a storage medium and an electronic device. The method comprises the following steps: monitoring data of the power station equipment is obtained, the monitoring data comprises real-time monitoring data and gathered monitoring data, the real-time monitoring data is greater than the gathered monitoring data in collection frequency, the real-time monitoring data is compared with first prediction data in real time to determine an operating state of the power station equipment, and the gathered monitoring data is compared with second preset data to determine performance of the power station equipment. According to an operating state of the power station equipment and the performance of the power station equipment,whether faults occur in the power station equipment is monitored. Therefore, a problem that the operating state of the power plant equipment cannot be accurately monitored via relevant conventional technologies can be solved, and effects of real-time and accurate monitoring of the operating state of the power plant equipment can be achieved.
