Problems solved by technology

[0003] However, distributed power plants are scattered and small in scale. If decentralized operation and maintenance management, labor costs will be high, which will affect the return on investment. Therefore, a method of intelligent centralized monitoring and management of photovoltaic power plants is needed to solve this problem.
The existing intelligent monitoring methods can meet the management needs of large-scale ground power stations, but it is not very practical for the supervision of distributed power stations, because the follow-up operation and maintenance costs are too high; A simple analysis of the data shows, such as power generation, system PR, based on historical radiation data (average of the past 10 years) to estimate the power generation situation in the future, the error is large

Abstract

The invention discloses a method and a system for intelligent centralized monitoring and management of a photovoltaic power station. The method includes the steps: acquiring and analyzing meteorological data of the photovoltaic power station; acquiring signals of an inverter, a circuit breaker and a transformer of the photovoltaic power station and receiving remote control signals to control related modules; acquiring voltage, current and component temperature data of each sub-module of the photovoltaic power station; converting the data into proper protocols, transmitting the protocols to a network switch through a network and finally transmitting the protocols to a monitoring computer and a server; displaying the data. Operation, maintenance and management of the distributed power station are realized by the centralized monitoring and management method, the data of the photovoltaic power station are deeply analyzed, the problem of shortage of data statistics of the photovoltaic power station is solved, and the operation and maintenance management mode of the photovoltaic power station is optimized.

Description

technical field [0001] The invention relates to a method and system for intelligent centralized monitoring and management of a photovoltaic power station. Background technique [0002] The construction of photovoltaic power stations has shifted from large-scale ground-based grid-connected power generation to distributed self-consumption. Distributed power stations have almost no impact on the environment. control. [0003] However, distributed power plants are scattered and small in scale. If decentralized operation and maintenance management, labor costs will be high, which will affect the return on investment. Therefore, a method of intelligent centralized monitoring and management of photovoltaic power plants is needed to solve this problem. The existing intelligent monitoring methods can meet the management needs of large-scale ground power stations, but it is not very practical for the supervision of distributed power stations, because the follow-up operation and maint...
