Energy efficiency deviation rectification control method and device for public building electromechanical system

Abstract

The invention discloses an energy efficiency deviation rectification control method and device for a public building electromechanical system, and the method comprises the steps: carrying out the format processing of historical load data of a target electromechanical system in a preset time period, and obtaining preset imported data; performing load prediction on the preset imported data through apreset algorithm, and obtaining an energy efficiency prediction result based on comparison between the simulation data and the test data; implanting the energy efficiency prediction result into the control loop of the target electromechanical system through a network, and obtaining the control strategy of the target electromechanical system through prediction control; and optimizing the control strategy based on a multi-target particle swarm algorithm so as to control and output the optimal operation strategy of the target electromechanical system. According to the energy efficiency deviationrectification control method and device, the high-energy-efficiency operation interval of the existing building electromechanical system is automatically recognized by automatically collecting historical operation data of the system, and long-term efficient and stable operation of the existing building electromechanical system is achieved through the control logic of energy efficiency setting, threshold deviation, real-time rectification control and automatic optimization.

Description

technical field [0001] The invention relates to the control field of electromechanical systems of public buildings, in particular to an energy efficiency deviation correction control method and device suitable for electromechanical systems of public buildings. Background technique [0002] In my country, the cooling and heat loss of the building envelope and the energy consumption of ventilation and air conditioning system equipment account for more than 50%, and the energy consumption of lighting and power systems accounts for more than 30%. It can be seen that the main energy consumption of building energy consumption is air conditioning and lighting, and this is exactly It is also the two items that reflect the comfort level. In order to ensure a good comfortable environment, people usually sacrifice more energy consumption to meet the needs of the human body. At present, due to the different construction standards and ages of existing public buildings in my country, the c...
