Mains-supply home electricity consumption control system with combined-sealing triode

Abstract

The invention discloses a mains-supply home electricity consumption control system with a combined-sealing triode. The mains-supply home electricity consumption control system comprises a monitoring terminal and a home power distribution terminal connected with the monitoring terminal. The home power distribution terminal comprises an AC / DC (alternating current / direct current) conversion circuit,a high-frequency transformer, a charging control circuit, a storage battery, a discharging control circuit, a current detection module, a voltage detection module, an intelligent controller and a security and protection module. The mains-supply home electricity consumption control system has the advantages of multiple protection, measurement accuracy, high reliability, practicability, high intellectualization, low cost and the like, home electricity consumption cost can be reduced effectively, and effective energy conservation of home electric appliances is benefited; external starting circuits are omitted due to an AC-DC conversion device, and power consumption of the starting portion is reduced greatly; the combined-sealing triode is used for starting, so that stand-by power consumptionis low, and speed is high; the combined-sealing technology is adopted, so that a high pressure process is not need, easiness in implementation is achieved, and cost is saved; in case of output short circuit, the system enters a fixed frequency mode automatically, and stability is improved.

Description

technical field [0001] The invention belongs to the field of intelligent control of power distribution, and in particular relates to a mains household electric control system using sealed transistors. Background technique [0002] With the introduction of the smart grid concept, energy metering and marketing programs based on home smart interactive terminals have been gradually formed, which means that home control will move towards intelligence. Smart home is a new type of home that has emerged and risen rapidly in recent years. The intelligence of home provides residents with a more secure, comfortable, convenient, fast and open intelligent and informational living space. It is convenient for users. Therefore, it is of great significance to the transformation and implementation of the smart grid to establish a set of home control system with the home interactive terminal as the core. [0003] As the penetration rate of Distributed Energy Resource (DER) continues to incre...

AI Technical Summary

Problems solved by technology

The access of DER to the distribution network may bring problems to the power grid, such as affecting the short-circuit level, affecting reactive power and voltage distribution, especially the plug-and-play access of new energy, which brings more problems to the operation of the distribution network. The uncertainty of the distribution network makes it more difficult to control
