摘　　要：为了解决海拉尔市区供热能力缺口问题,华能蒙东公司实施了伊敏电厂长距离供热改造项目。根据海拉尔市区的供热现状,针对长输供热管网3000~10000 t/h流量的多种工况,开展了仿真计算与压力水头的分析,制定了以降低外购电为目标的泵组运行策略。通过两个供暖期的运行对比,应用了泵组运行策略的供暖期节约外购电645.59万千瓦时,节省外购电成本369.76万元,验证了泵组运行策略的经济优势。With the target of solving the heating curtail problem in Hailar,Huaneng Mengdong company implemented the long-distance heating renovation project of Yimin thermal power plant.In this paper,according to the current heating situation in Hailar,hydraulic simulation and pressure head analysis are carried out in different working conditions of long-distance network between 3000 t/h and 10000 t/h,and the operational strategies are formulated with the objective of lowering the external electricity purchase.The economic benefits of the operational strategy are demonstrated through the comparison of two heating seasons,which are a 6455900 kW·h decrease of external electricity and a 3697600 CNY retrenchment of external purchase cost.
