A new energy photovoltaic box change measurement and control system and its remote program version management method

Abstract

The invention provides a new energy photovoltaic box transformer substation measurement and control system and a remote program version management method thereof. The new energy photovoltaic box transformer substation measurement and control system comprises a box transformer substation measurement and control device, a box transformer substation measurement and control program version management server, a photovoltaic power station box transformer substation measurement and control program version client, and a program version maintenance function module residing in the box transformer substation measurement and control device. The remote program version management method of the new energy photovoltaic box transformer substation measurement and control comprises the following steps of monitoring each photovoltaic power station connection request by the box transformer substation measurement and control program version management server; and when the box transformer substation measurement and control program version management server receives a connection request of a photovoltaic power station client, creating a new program maintenance thread, requesting a latest program list by the client, returning a latest order model and supporting a latest version program by the server, and synchronously returning a designated photovoltaic power station non-standard program order model and the latest version program of the non-standard program. The new energy photovoltaic box transformer substation measurement and control system and the remote program version management method thereof provided by the invention can overcome the defects of large workload and error prone in manual updating, save manpower and material resources, improve work efficiency, and have good real-time performance.

Description

technical field

[0001] The invention relates to a new energy photovoltaic box-station measurement and control technology, in particular to a new energy photovoltaic box-station measurement and control system and a remote program version management method thereof. Background technique

[0002] The measurement and control device of the photovoltaic box-type transformer is an important secondary equipment of the photovoltaic project. Collect the information of on-site inverters, combiner boxes and on-site meteorological equipment, and send the collected information to the photovoltaic monitoring system of the step-up station through communication protocols such as IEC 104. The traditional program version management method is that the engineers carry out version confirmation and upgrade one by one on site. Due to the large number of photovoltaic power station projects, there are many projects with a large number of box-type transformer measurement and control devices used in a s...
