模块化智能变电站精准送风系统能效管理优化策略OACSTPCD

In the existing modular smart substations,the internal environment control of the intelligent control cabinet is not balanced,the local temperature exceeds the safe operating range of the equipment,and the energy efficiency is rarely considered.In this paper,an energy efficiency management optimization strategy for precision air supply sys-tem of modular smart substations is proposed.Firstly,the mathematical models of heat exchange and air flow in the air conditioning system and the air flow in the pipeline system are established.On this basis,the optimization meth-od of energy efficiency management of the precision air supply system is put forward,taking the minimum energy consumption of the control system as the objective function.The efficient solver CPLEX is used to obtain the control strategy with the lowest energy consumption.The steady-state process analysis is carried out by ANSYS Icepak,and the stability of the system operation is verified.The results show that the proposed method can achieve accurate control of the internal environment of the intelligent control cabinet,and achieve the purpose of green and low-car-bon operation of the system.
