Comprehensive electrical performance field movable detection method for large-scale ground photovoltaic power station

Abstract

The invention provides a comprehensive electrical performance field movable detection method for a large-scale ground photovoltaic power station. The comprehensive electrical performance field movable detection method comprises the following steps of 1, opening analysis equipment and multiple detection equipment; 2, correcting the detection equipment in sequence by the analysis equipment, such as adopting unified clock correcting time until synchronization of the multiple detection equipment is achieved; 3, conveying and connecting the first, the second until the N detection equipment to the first, the second until the N detected equipment in sequence, and starting detection in connecting; and waiting for continuous detection for a certain time; 4, recovering the N until the second and the first detection equipment in sequence; 5, reading detection data in the N detection equipment by the analysis equipment, screening out synchronous data at the same moment detected by all the N detection equipment, comparing and finding the minimum data, corresponding to a serial number of the detected equipment, namely finding out short slab equipment; and 6, performing test diagnosis and maintenance and efficiency improvement for the short slab equipment to complete the detection.

Description

[0001] Technical field [0002] The invention relates to the technical field of on-site power generation performance detection of photovoltaic power stations, in particular to the technical field of a method for on-site mobile detection of comprehensive electrical performance of large-scale ground photovoltaic power stations.

Problems solved by technology

However, the detection modules that come with these devices are only auxiliary functions of their main functions, and the accuracy is not high, the consistency is not good, and some modules have deviations after the equipment has been running for a long time, and even a large number of modules and communication lines are damaged, resulting in automation. The monitoring system cannot obtain data or the obtained data cannot be directly used

[0005] These problems are obstacles to the operation and maintenance management of photovoltaic power plants, power plant performance improvement, and power plant revenue improvement. Therefore, it is necessary to invent a new system to solve these problems
