Method and system for continuously supplying power by solar energy and commercial power

Abstract

The invention relates to a method and a system for continuously supplying power by solar energy and commercial power. The method comprises the following steps of: 1, judging whether communication between a solar energy system and a commercial power system is normal or not, and if the communication is normal, performing a step 3, and if the communication is abnormal, performing a step 2; 2, setting the commercial power system in a fixed floating charge state; and 3, automatically managing the commercial power system on the basis of information acquired from the solar energy system and automatically managing the solar energy system on the basis of the information acquired from the commercial power system. The method and the system for continuously supplying power by the solar energy and thecommercial power are used for performing automatic management on the commercial power system on the basis of the information acquired from the solar energy system and performing the automatic management on the solar energy system on the basis of the information acquired from the commercial power system through the communication between the solar energy and the commercial power system, and thus realizing perfect combination of the solar energy and the commercial power to provide reliable power supply which is not influenced by switching time.

Description

technical field [0001] The invention relates to a power supply system, and more specifically, relates to a method and system for continuous power supply of solar energy and mains power. Background technique [0002] The AC mains system has always occupied most of the electricity market because of its stability and continuity. However, with the development of society, people pay more and more attention to energy saving. Solar energy has been widely used due to its non-polluting, renewable and inexhaustible advantages. However, due to weather or other reasons, solar energy may be discontinuous in time and power, which brings inconvenience to many utilization occasions. Therefore, some areas have formed a power supply mode that uses solar energy and mains power systems as complementary power supplies. [0003] For example, Chinese utility model patent application ZL200620153408.3 discloses a complementary solar uninterruptible power supply controller, which includes a multif...
