An Intelligent Monitoring System for Photovoltaic Box Transformers

Abstract

The invention discloses an intelligent monitoring system for a photovoltaic box change, which includes a high-voltage room detection module, a transformer room detection module, a low-voltage room detection module, a communication module, and a monitoring center module; the high-voltage room detection module, the transformer room detection module, the low-voltage The room detection module is connected with the control management module through the communication module respectively. The intelligent monitoring system of the photovoltaic box-type transformer of the present invention adopts the design concept of integration of measurement, control, protection and communication, which simplifies the wiring of the entire photovoltaic power generation unit, reduces the workload of engineering commissioning and later maintenance, reduces the investment cost of photovoltaic power plants, and realizes Intelligent monitoring is achieved; at the same time, the communication module uses two optical fiber communication modules and CPLD digital control technology, which can realize the self-healing of the optical fiber ring network.

Description

technical field [0001] The invention belongs to the technical field of control of photovoltaic box-type transformers, and in particular relates to an intelligent monitoring system of photovoltaic box-type transformers. Background technique [0002] Photovoltaic grid-connected power generation began in the early 1980s. The so-called photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. power generation device. Photovoltaic box change is a kind of AC power conversion device. First, the DC power is converted into AC power through the inverter, and then the AC voltage and current of a certain value can be converted into another value of AC voltage and current of the same frequency, so that the power transmission , distribution and use, so as to be safe and economical. [0003] The automatic monitoring system plays an important role in the photovoltaic power station...

AI Technical Summary

Problems solved by technology

With the maturity of photovoltaic power station technology, the equipment in the photovoltaic power station is relatively scattered. According to the traditional automatic monitoring system, more communication management cabinets need to be arranged on the spot, which increases equipment investment. The probability of failure is reduced, which is not conducive to the investigation of system failure in the future
