Description

technical field [0001] The invention relates to the application field of renewable energy power generation, in particular to a station-use UPS power supply control system for coordinated power supply of solar energy and municipal power. Background technique [0002] At present, with the outbreak of the global energy crisis, the world's energy sources are facing enormous pressure and challenges. Therefore, new renewable energy has become a rookie and has gradually gained people's favor, and solar energy is one of the most concerned new energy sources. With the development and wide application of substation integrated automation technology, the level of automation has been continuously improved. The integrated automation system has realized microcomputer background monitoring, protection fault information uploading, electric energy metering, dispatching data network communication, telecontrol terminal services, etc. To ensure that these devices can play their roles reliably, ...

Problems solved by technology

But at the same time, this online UPS system has another big disadvantage. In order to ensure long-term stability of energy consumption at the load end, the municipal power grid must continuously deliver AC power to the UPS system, and it needs to be converted during specific use. It can only be used for DC power and then re-inverted, which makes the UPS power system encounter huge obstacles in the development, and then leads to a great reduction in the efficacy of the UPS power system in alleviating the energy crisis and improving conversion efficiency
