±1100 kV户内直流场通风与空调运行效果探讨

Discussion on Ventilation and Air Conditioning Operation Effect of ±1100 kV Indoor DC Yard

本文以新疆的某个1100 kV特高压户内直流场作为案例,结合实际情况分别提出全程通风系统及通风与空调系统联合系统调控运行方案,运用Fluent数值模拟对两运行模式下室内流场情况进行对比分析,结果表明,户内直流场采用通风送风方案时,室内温度不均匀系数更小,能量利用系数更大,但是温度安全保证系数更低。

Taking a 1100 kV UHV indoor DC field in Xinjiang as an example, this paper puts forward the control and operation schemes of ventilation system and ventilation combined air conditioning system, and compares the indoor flow field under the two operation modes by using fluent numerical simulation. When the ventilation and air supply scheme is adopted, the indoor temperature inhomogeneity coefficient is smaller and the energy utilization coefficient is larger, but the temperature safety guarantee coefficient is lower.
