on April 9, the luoshan county power supply company of the national network relied on the reverse heavy overload data set in the photovoltaic station area of the “digital intelligence and power” platform to solve the heavy overload problem caused by photovoltaic grid connection by digital means and build a new energy grid connection safety defense line.
Since the beginning of this year, with the continuous access of distributed photovoltaics to the power grid, the problem of reverse heavy overload of lines in rural distribution stations has become increasingly prominent. According to statistics, the reverse heavy overload data set of the photovoltaic station area of the “Digital Intelligence Yudian” platform gathers real-time measurement data of the photovoltaic station area of the whole province, and can monitor 7 key data such as the photovoltaic capacity of the station area, the reverse heavy overload state of the station area, the maximum load rate and the start time of continuous heavy overload.
up to now, the company has accumulated more than 50 lines involving photovoltaic reverse overload problem in Luoshan county by using the platform data set. 112 high-risk stations have been identified by using the platform data and previous data analysis, and the hidden danger discovery efficiency has been improved by 45%.
This PV reverse heavy overload statistics is a key measure for the company to deepen the use of the platform. In the next step, luoshan county Power Supply Company of the State Grid will monitor the heavy overload lines and stations in a timely manner, and gradually realize the full coverage monitoring of 100 photovoltaic stations , so as to promote the coordinated development of power grid and new energy sources with digital intelligence and provide strong power guarantee for rural revitalization.
