Problems solved by technology

[0002] Power supply is everywhere, and the consumption process of electric energy develops rapidly with nonlinear loads. Power quality problems pose a potential serious threat to the safety and stability of the power system itself, and also cause harm to the power distribution system at the user end.
Because the traditional power distribution control method is mainly through the combination of circuit breakers, contactors, thermal relays, fuses, transformers and various electrical instruments (current, voltmeter, power meter, power factor meter, energy meter) into a switch cabinet to achieve distribution. Power, control, protection, monitoring and other functions, and mainly manual direct operation, unable to realize computer intelligent management

Abstract

The invention relates to a client distribution intelligent system, comprising a display, a host, and a serial server which are successively in connection, and an electric energy quality on-line monitoring control device, a dynamic filtering compensation automatic controller and microcomputer on-line monitoring protection devices which are in connection with the serial server through an on-site bus. The system can guarantee the safe, stable and economic operation of client distribution system electrical equipment, and discover in an early stage hidden troubles of a distribution system so as to take measures for prevention. The system possesses the energy saving effects of: (1) eliminating harmful harmonic wave, improving electric energy quality and power factor, and reducing line loss; (2) balancing three phase power, prolonging the service life of equipment, and reducing operation costs through monitoring and analyzing electric energy quality; and (3) collecting the data of each electrical terminal under a software interface to perform visual management, and realizing electricity utilization controllable and adjustable according to actual electricity utilization demands, thereby reducing unnecessary electric energy consumption, and saving electricity.

Description

technical field [0001] The invention relates to a power distribution system at a user end of a power system, and more specifically, to an intelligent system for power distribution at a user end. Background technique [0002] Power supply is everywhere, and the consumption process of electric energy develops rapidly with nonlinear loads. Power quality problems pose a potential serious threat to the safety and stability of the power system itself, and also cause harm to the power distribution system at the user end. Because the traditional power distribution control method is mainly through the combination of circuit breakers, contactors, thermal relays, fuses, transformers and various electrical instruments (current, voltmeter, power meter, power factor meter, energy meter) into a switch cabinet to achieve distribution. Power, control, protection, monitoring and other functions, and mainly manual direct operation, unable to realize computer intelligent management. [0003] T...
