基于EBSILON仿真软件的联机供热负荷分配优化

针对某电厂供热能耗偏高,利用EBSILON仿真软件搭建了200 MW和300 MW机组的联机供热系统模型,获得机组最佳运行方式,有效缓解了联机机组能耗大、运行成本高的问题。在模拟过程中,对不同热电负荷进行计算模拟,得到机组总煤耗与发电标准煤耗随300 MW机组热电负荷占比的变化关系曲线。根据模拟结果得出:当300 MW机组发电量为250 MW至280 MW时,机组的经济性及安全性最佳。为确定联机机组最佳热电负荷分配提供了理论支持,实现了节能减排、能耗降低的目标。

Optimization of heating load distribution of combined unit based on EBSILON simulation software

In view of the high heat energy consumption of a power plant, the system model of 200 MW and 300 MW combined unit was built by EBSILON simulation software, and the optimal operation mode of the unit was obtained, which effectively alleviated the problems of large energy consumption and high operation cost of combined unit. In simulation process, different distribution of heat and power load was calculated. When the proportion of heat and power load of 300 MW unit changed, the corresponding change curves of the total coal consumption of the unit and the standard coal consumption for generation power were obtained. The simulation results showed that, the economy and safety of the unit were the best when the generating capacity of 300 MW unit was 250 MW to 280 MW. The results provided theoretical support for determining the optimal heat and power load distribution of combined unit, and achieved the goals of energy saving, emission reduction and energy consumption reduction.
