Intelligent energy supply control system and method based on light storage and residual heat and residual pressure power generation

Abstract

The invention relates to an intelligent energy supply control system and method based on light storage and residual heat and residual pressure power generation. A common miniature residual heat and residual pressure power generation system is not provided with an individual control system, and cannot achieve integrated management demands of management of a plurality of energy input, electric energy quality automatic adjustment, networking electric quantity control, load automatic control and the like. The intelligent energy supply control system comprises a residual pressure power generation intelligent energy supply management system, a grid connected module, a residual pressure power generation input control module and a photovoltaic input control module. A residual pressure power generation input interface is connected with the residual pressure power generation input control module, a photovoltaic power generation input interface is connected with the photovoltaic input control module, a load power utilization output interface is connected with a load power utilization output control module, a power generation system auxiliary power supply input interface is connected with a power generation system auxiliary power supply control module, and an energy storage system module is connected with an energy storage system control module. According to the invention, functions of multiple power supply input management, load output control and management, grid connected and off-grid operation management and the like are achieved.

Description

technical field [0001] The invention relates to an intelligent energy supply control system and method based on photovoltaic storage and waste heat and pressure power generation, which are mainly applied to energy saving and environmental protection systems and distributed energy systems. Background technique [0002] Utilizing the technology of converting excess heat energy into electrical energy in the production process, waste heat power generation not only saves energy, but is also conducive to environmental protection. The important equipment for waste heat power generation is the waste heat boiler, which uses the heat or combustible substances in waste gas, waste liquid and other working fluids as a heat source to produce steam for power generation. Waste heat power generation faces many problems like other distributed power sources. There are problems such as the operation and management mechanism of waste heat power generation devices, unit reliability problems, insu...

AI Technical Summary

Problems solved by technology

Waste heat power generation faces many problems like other distributed power sources. There are problems such as the operation and management mechanism of waste heat power generation devices, unit reliability problems, insufficient policy support, and poor operability. These are the bottlenecks restricting waste heat power generation in my country

[0003] Ordinary small waste heat and pressure power generation systems are not equipped with a separate control system. Generally, a power distribution system is composed of 0.4kV switch cabinets, which cannot realize the management of various energy inputs, automatic adjustment of power quality, online power control, automatic load control, etc. Integrated Management System

However, the power company has strict restrictions on power quality and on-grid electricity. If the power quality and on-grid electricity cannot be guaranteed, it will be difficult to meet the demand

[0004] At present, there are also some technologies that utilize waste heat and pressure to generate electricity. For example, the publication date is April 03, 2013, and the publication number is CN202849450U in a Chinese patent, which discloses a power generation system that recycles blast furnace gas residual pressure and waste heat. In the Chinese patent dated September 22, 2010, the publication number is CN101839154A, a distributed waste heat and pressure power generation system and a distributed waste heat and pressure power generation method are disclosed, but these technologies are difficult to achieve multiple power input management, Load output control and management, grid-connected and off-grid operation management, online management, power quality monitoring and control, load control, protection and other functions
