| 针对现有模块化智能变电站中智能控制柜内部环境控制不均衡、存在局部温度超出设备安全运行范围且较少考虑能效的问题，提出一种模块化智能变电站精准送风系统能效管理优化策略。首先建立空调系统热交换和管道系统空气流量数学模型，在此基础上以控制系统运行能耗最低为目标函数，提出了精准送风系统能效管理优化方法。采用高效的求解器CPLEX求解，得到能耗最低的控制策略。并通过 ANSYS Icepak进行稳态过程分析，验证了系统运行的稳定性。结果表明所提方法能够实现对智能控制柜内部环境的精准控制，达到了系统绿色低碳运行的目的。 |

| 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 system 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 method 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-carbon operation of the system. |
