Embodiment Construction

[0039] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0040] The preferred embodiment of the present invention provides an automatic intelligent power distribution system, which is used for distributing electric energy from three-phase transmission lines to single-machine users on the low-voltage side. refer to figure 2 , 10KV / 380V / 220V distribution transformer first converts high-voltage electricity into low-voltage electricity for domestic use, and the low-voltage side of the distribution transformer is divided into multi-channel three-phase low-voltage transmission lines through multi-channel air switches and AC contactors. Taking a three-phase low-voltage transmission line as an example, the automatic intelligent power distribution system of the present invention includes a power distribution moni...

Abstract

The invention discloses an automatic intelligent power distribution system and a power distribution method. The power distribution system comprises a power distribution executing unit, and the power distribution executing unit receives a power distribution command from a power distribution monitoring terminal and gates a corresponding phase line on a three-phase power transmission line to a single-phase power supply line on an output side of the power distribution executing unit to achieve intelligent power distribution. According to the automatic intelligent power distribution system, low-voltage three-phase disequilibrium distribution on an input side of a single-phase user is achieved through the power distribution executing unit on an input side of an electricity meter of the single-phase user, the power distribution monitoring terminal receives the electrical load information of each single-phase user in a wireless or power line carrier communication mode, and a basis is provided for the equilibrium distribution of single-phase user quantity on each phase line of the three-phase power transmission line on the whole; the power distribution monitoring terminal sends the power distribution command to the power distribution executing unit and the power distribution executing unit enables each single-phase user to be connected to a corresponding power supply phase line in a grouping mode, and therefore equilibrium power distribution is achieved for single-phase users on a low-voltage side.

Description

technical field [0001] The invention relates to the fields of electric energy measurement and power supply, and in particular, to an automatic intelligent power distribution system and a power distribution method. Background technique [0002] With the continuous improvement of people's living standards, a large number of high-power single-phase household appliances, such as: air conditioners, electric water heaters, rice cookers, microwave ovens, ovens, etc., have entered ordinary households. These household appliances bring people comfort, convenience and fast life. , It also has a certain impact on the safety and economic operation of the low-voltage power supply system of the power supply department. refer to figure 1 , the existing power supply network leads three three-phase power supply lines from the low-voltage side of the 10KV / 380V / 220V distribution transformer through the air switch and AC contactor, and the A-phase, B-phase, and C-phase lines of each three-phase...
