ELECTRICITY-SAFETY MANAGING SERVER AND METHOD FOR MANAGING OF ELECTRICITY-SAFETY}

The present invention relates to an electrical safety management technology, and more particularly, to an electrical safety management method and system for determining whether a photovoltaic power generation system and an energy storage system are abnormal.

In general, a photovoltaic system is a technology that directly converts solar energy into electrical energy using the photovoltaic effect.

Photovoltaic power generation system that can supply power is composed of a solar cell module which is a semiconductor device, a storage battery that stores power, and an inverter that converts direct current electricity into alternating current.

Photovoltaic systems have the advantages of no fuel, no thermal pollution and no environmental pollution. In addition, there are no risks such as noise pollution, radiation hazards and explosions. Furthermore, the operation and maintenance of the photovoltaic system is simple and unmanned.

However, due to the high cost of power generation, the economic feasibility is weak, and the amount of power generation is not constant because it is limited by the time that can be developed by the limited sunshine time according to weather conditions.
