枝状流体供热网优化运行策略研究与实现

Research and Realization of Optimal Working Strategic of Branched Fluid Heating Network

针对现行的控制策略不能很好的实现供热网的优化运行,首先提出了基于启发式加权交叉算子的实数编码遗传算法。并在建立了供热网运行成本的模型后,应用改进型遗传算法对运行成本进行优化,即通过对优化模型中一次侧流量和二次侧供水温度的调节,实现运行成本节约,达到均匀、1按需供热。在此基础上,利用仿真技术可以对已有管网运行进行分析,还可以对未建管网进行优化设计。

Aim at present control strategy is too weak to solve the optimal operating problem of district heating network, firstly, a new real-coded genetic algorithms based on heuristic weighted crossover operator is proposed. Secondly, after the model of working cost setting up, the improved genetic algorithms could optimize the working cost of district heating network. In ＇order to cut clown the working cost, the rate of flow in the primary heating network and the temperature of supplying water in the＇ secondary heating network are regulated. It keeps every substation balance and the temperature in the house meets people needs. And based on this, simulation technology could be utilized to analyze operation of existing heating network and to design pipeline.
