Problems solved by technology

[0005] In the construction process of the existing household micro-grid system, the large-scale industrial and commercial micro-grid model is applied. New energy equipment such as photovoltaic power generation and wind power generation adopts a separate access mode. At the same time, complex micro-grid measurement and control protection, mode control, and energy management systems are configured. , although the grid-connected operation of the micro-grid works well, the engineering volume of the micro-grid system is large and the cost is high, which does not meet the actual situation of the household micro-grid
At the same time as the traditional home switch, the traditional micro-grid construction method has limitations in data transmission, and cannot meet the real-time query and control management requirements of home users for the status of electrical equipment.

Abstract

The invention provides an intelligent switch control method suitable for a family micro-grid. The intelligent switch control method comprises the steps as follows: a main outgoing line switch detects voltage and current of electric supply in real time; a branch switch detects the voltage of various branches and the current of the branches in real time and transmits the voltage and the current to an operation module; voltage and current data are transmitted to the operation module; the operation module calculates active power and reactive power of a main outgoing line and the active power and the reactive power of the branches and analyzes the current power grid state; the operation module judges whether the power grid state is normal or not by detecting the voltage of the electric supply to control on / off of the main outgoing line switch; the main outgoing line switch is in a grid-connected mode when switched on and the main outgoing line switch is in an off-grid mode when switched off; and on / off modes of the branch switches in the grid-connected mode or the on / off modes of the branch switches in the off-grid mode are formed through analysis of the active power of the branches. By the intelligent switch control method suitable for the family micro-grid, effective isolation of the family micro-grid in normal power supply and an unscheduled power failure of the electric supply can be ensured; the energy efficiency level is improved; and meanwhile, the economic benefits of system operation are also improved.

Description

Technical field [0001] The invention relates to an intelligent switch control method. In particular, it relates to an intelligent switch control method suitable for household micro-grid. Background technique [0002] With the increasing requirements for the quality of living standards and the increasing popularity of new energy power generation technologies, the home microgrid has become an important unit in modern electricity. The so-called microgrid refers to a single controllable independent power generation system composed of distributed power generation, loads, energy storage devices and control devices. The home microgrid is based on residential users' houses. Photovoltaic power generation, wind power generation and energy storage devices and other clean energy and smart homes and other electrical equipment build a microgrid system. [0003] With the increasing requirements for the quality of living standards and the increasing popularity of new energy power generation tech...
