In view of the heat compensation equipment widely used in combined heat and power (CHP)plant, the feasible operation region model and coal-saving rate model of the CHP plant equipped with a solid heat storage electric boiler are constructed. The effects of the solid heat storage electric boiler, the electrode electric boiler and the water storage heat accumulator on the heat-supply capacity, regulation ability and operation cost of the CHP plant are compared and analyzed. Based on the current status of a CHP plant, a general model for combined dispatching of the CHP plant with flexibility to configure heat compensation equipment is established. Combining with the actual operation data of the CHP plant, the above models are verified and the differences in operation flexibility, scene adaptability, coal-saving effect and operation cost among different heat compensation equipment are quantitatively analyzed. The results show that under the same heating capacity, the solid heat storage electric boiler has the strongest flexibility and the lowest coal saving rate. The heat accumulator has the best coal-saving effect, but the scene adaptability is lower than other heat compensation schemes. The model and research results can provide theoretical tools and reference for the optimal operation of CHP plants.

针对热电企业广泛应用的供热补偿设备,构建了抽凝机组配置固体蓄热式电锅炉后的电热可行域模型以及节煤率模型,对比分析了固体蓄热式电锅炉与电极式电锅炉、储水式蓄热罐对热电机组在供热能力、调峰能力、运行成本3方面的影响。基于当前热电企业现状,对配置供热补偿设备的灵活性热电厂建立了电热联合调度通用模型,结合实际热电厂运行数据,校验了上述模型并量化分析了不同补偿供热方案在运行灵活性、场景适应性以及节煤效果、运行成本方面的差异性。结果表明:同等供热能力下,固体蓄热式电锅炉灵活性最强,节煤效果相对最弱,节煤率仅为0.11;蓄热罐节煤效果最佳,节煤率达到0.27,但其场景适应性不及其他供热补偿方案。本文所建模型与研究结果可为热电企业的优化运行提供理论工具及参考。

针对热电企业广泛应用的供热补偿设备,构建了抽凝机组配置固体蓄热式电锅炉后的电热可行域模型以及节煤率模型,对比分析了固体蓄热式电锅炉与电极式电锅炉、储水式蓄热罐对热电机组在供热能力、调峰能力、运行成本3方面的影响。基于当前热电企业现状,对配置供热补偿设备的灵活性热电厂建立了电热联合调度通用模型,结合实际热电厂运行数据,校验了上述模型并量化分析了不同补偿供热方案在运行灵活性、场景适应性以及节煤效果、运行成本方面的差异性。结果表明:同等供热能力下,固体蓄热式电锅炉灵活性最强,节煤效果相对最弱,节煤率仅为0.11;蓄热罐节煤效果最佳,节煤率达到0.27,但其场景适应性不及其他供热补偿方案。本文所建模型与研究结果可为热电企业的优化运行提供理论工具及参考。

In view of the heat compensation equipment widely used in combined heat and power (CHP)plant, the feasible operation region model and coal-saving rate model of the CHP plant equipped with a solid heat storage electric boiler are constructed. The effects of the solid heat storage electric boiler, the electrode electric boiler and the water storage heat accumulator on the heat-supply capacity, regulation ability and operation cost of the CHP plant are compared and analyzed. Based on the current status of a CHP plant, a general model for combined dispatching of the CHP plant with flexibility to configure heat compensation equipment is established. Combining with the actual operation data of the CHP plant, the above models are verified and the differences in operation flexibility, scene adaptability, coal-saving effect and operation cost among different heat compensation equipment are quantitatively analyzed. The results show that under the same heating capacity, the solid heat storage electric boiler has the strongest flexibility and the lowest coal saving rate. The heat accumulator has the best coal-saving effect, but the scene adaptability is lower than other heat compensation schemes. The model and research results can provide theoretical tools and reference for the optimal operation of CHP plants.
