Multiple fully-automatic large-horsepower high-speed integrated parallel and commercial power interconnection system and power supply method thereof

Abstract

The invention discloses a multiple fully-automatic large-horsepower high-speed integrated parallel and commercial power interconnection system and a power supply method thereof, wherein the multiple fully-automatic large-horsepower high-speed integrated parallel and commercial power interconnection system comprises a large-power diesel generating unit, a unit grid-connected cabinet, a commercial power wire entering cabinet, a unit controller, a power management system, a DCS monitoring system, a high-temperature tail gas residual heat utilizing system, and a load output cabinet. By the matching among all functional modules, the power transmission (power sale), peak load shifting, peak load reducing and the power consumption during the shutdown process of the commercial power can be realized effectively; compared with the diesel generating equipment that is widely applied in a dispersed way in the traditional technology, on one hand, the whole process has the advantages of being operated simply, and fully realizing unmanned operation and remote control and diagnosis; on the other hand, the whole system can output the electric energy according to the requirement by the change of theload, thus effectively controlling unnecessary waste and reducing cost invisibly. Furthermore, the large-power diesel generating unit generates low noise and has low quality requirement on fuel; and the fuel has low consumption rate and low emission rate.

Description

technical field [0001] The invention relates to the technology in the field of power systems, in particular to a multi-unit high-horsepower high-speed fully automatic integrated parallel connection and grid-connected system and a power supply method for a small power station in a new type of industrial area. Background technique [0002] At present, people's lives are often disturbed by power outages due to special weather that damages the power transmission system, artificially cut off power cables, or limited supply of power due to excessive demand on the grid. Diesel power generation equipment is widely used in the market to maintain normal power supply in case of mains failure or power failure. The application of diesel power generation equipment has been gradually applied to households from factories and markets. [0003] However, since most of the existing diesel power generation equipment is used in a decentralized manner, it has the following disadvantages: [0004]...

AI Technical Summary

Problems solved by technology

[0004] Generally, it is manually operated, and its operation is more complicated. There is no timely and reasonable control of the entire power supply process, and it only realizes a rough power supply function; and the decentralized application of diesel power generation equipment is not easy to manage, and its exhaust emissions and waste heat It is difficult to deal with it reasonably, so that the application of countless scattered diesel power generation equipment makes the pollution and energy waste change from small to large, and its impact is actually extremely serious
