Monitoring method of photovoltaic power generation system and system thereof

Abstract

The invention provides a monitoring method of a photovoltaic power generation system and a system thereof. The method comprises the classified collection, classified storage, service provision and classification application. The classified collection comprises the real-time data collection, periodic data collection and the event data acquisition of equipment in a system. According to the data, the provided service comprises state management, equipment control, exclusive management, alarm recognition, task management and log management. The operated application comprises operation monitoring, remote control, alarm notification, video surveillance, analysis and diagnosis, comprehensive inquiry, statistical reporting and equipment management. According to the monitoring method and the system, the real-time monitoring and control of the main equipment in a solar photovoltaic power station is carried out, the operation of the power station is rapidly grasped through various styles of charts and data, the completely reliable and stable operation of a solar photovoltaic power generation system is ensured through a user-friendly interface, powerful analysis functions and perfect fault alarm, and remote off-site maintenance and multi-people cooperation are facilitated to realize secondary configuration development.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation and electric power production, and in particular relates to a monitoring method and system for a photovoltaic power generation system. Background technique [0002] From the current situation and prospects of photovoltaic grid-connected development, it can be seen that the photovoltaic industry is developing rapidly. In order to study the operating performance of these photovoltaic grid-connected power generation systems and optimize the design of photovoltaic power plants, the monitoring technology of photovoltaic grid-connected power generation And develop in depth. With new energy large-scale solar power plants starting construction and putting into operation one after another, it is necessary to centrally monitor, store, analyze, and display the operating status of photovoltaic power plants in order to master the operation management and operation experience of photovolta...

Problems solved by technology

If the scale of the power station is small, it is easy to deal with. The problem is that if the scale of the power station is large, the number of equipment is large, and the natural environment in remote areas is relatively harsh, the labor intensity of maintenance personnel under this maintenance management system is high, the management level is not high, and the relevant Most of the data and information exchange between departments is through paper reports or electronic files in a specific format. This method is costly and inefficient, and causes a lot of redundancy and inconsistency in data and information.

On the other hand, in addition to real-time system operation data for real-time system monitoring and related transaction management, a large amount of historical data needs to be saved for future statistical analysis, accident analysis, accident prediction, calculation and planning, but the current use of historical data rate is still quite low

In addition, due to the relatively remote and scattered distribution of photovoltaic power plants and the characteristics of a large area, the data collection display is too fragmented. If there is no centralized platform for centralized observation and data storage, it will cause inconvenience and difficulty in analysis and control.
