An off-grid integrated power supply control method and system

Abstract

The invention belongs to the technical field of electric power control, and discloses an off-grid integrated power supply control method and system. The off-grid integrated power supply control system includes: an electric energy collection module, a diesel power generation collection module, a wind power generation collection module, a photovoltaic Power generation acquisition module, electromagnetic switch control module, central processing module, wireless communication module, remote terminal, power generation module, signal conversion module, energy management module and power data analysis module. The invention can realize the integrated operation of the internal power supply and the load, and satisfy users' requirements on distributed power supply access, power quality, power supply reliability and safety. The invention can not only efficiently convert each input energy under the premise of maintaining the stability of the power grid, but also the intelligent distributed control management system can ensure the priority and efficient use of renewable energy, minimize the consumption of fuel, and ensure that the entire system Stable, safe and reliable operation and energy supply.

Description

technical field [0001] The invention belongs to the technical field of electric power control, and in particular relates to an off-grid integrated power control method and system. Background technique [0002] At present, the electricity used by residents is basically supplied by the mains power grid. In remote areas, such as mountainous areas, once the power grid system is damaged or natural disasters cause damage to the power grid system, the electricity consumption of residents will be disturbed. In milder cases, the power supply may be restored the next day, and in severe cases, there will be power outages for several days, which will cause great inconvenience to the lives of residents. [0003] Market survey analysis shows that the power supply system used by communication base stations is mostly the mains power provided by the grid, which supplies power to communication modules after rectification and DC / DC conversion. But in the long run, there are problems with such...

AI Technical Summary

Problems solved by technology

This type of power supply system requires high equipment costs. At the same time, due to the large difference in the use time of the off-grid inverter and the grid-connected inverter, the service life of the two inverters is also quite different, and the replacement cycle is different. Inconvenience to maintenance

[0005] Through the above analysis, the problems and defects of the existing technology are: the existing power supply system cannot realize the integrated operation of the internal power supply and the load, and the existing energy supply can only rely on one type, and the diversified supply of energy cannot be realized. And the system is unstable and not easy to maintain
