METHOD FOR MONITORING PHOTOVOLTAIC POWER GENERATION USING RTU, AND WIRELESS RTU DEVICE THEREOF

摘要

The present invention provides a photovoltaic power generation monitoring method of a remote terminal unit (RTU), comprising: receiving photovoltaic power generation state information via a ZigBee communication from a photovoltaic inverter; measuring the power of a ZigBee wireless communication signal and determining whether the power belongs to a normal range; performing transmit power control and low-noise amplifier (LNA) control on the basis of the determination result; generating a remote message on the basis of the received photovoltaic power generation state information and verifying the remote message; and transmitting the remote message to a monitoring server via a Wi-Fi communication. Accordingly, the photovoltaic power generation monitoring method of the present invention enables monitoring of photovoltaic power generation facilities to be conducted smoothly.
