Abstract

The present invention relates to an energy metering gateway for a photovoltaic power grid applied in the field of energy monitoring. In the process of monitoring the output power of a photovoltaic power generation system through a gateway terminal, the output power is compared with a normal power generation power trend collected in advance. When there is an obvious deviation, the light energy condition of the environment where the photovoltaic power generation system is located is first judged through a photovoltaic environment judgment system. When the light energy is in a stable state, it indicates that there is a possibility of failure in the photovoltaic power generation system or the gateway terminal. Subsequently, the environment temperature of the gateway terminal and the temperature of the gateway terminal itself are analyzed and judged, and the two are subjected to a separate cooling process when necessary, so as to judge whether the gateway has unstable operation or damage. The photovoltaic power grid fault condition is indirectly reflected through the integrity of the gateway, so as to carry out corresponding gateway fault warnings or photovoltaic power generation fault warnings, so that personnel can selectively prioritize the two.
