Electricity Power Plant Energy Saving Research Of Darat

本论文以达拉特发电厂为例,分析研究了火力发电厂厂用电的作用与构成情况,说明了直接影响发电厂用电率的是风机,泵类等大容量辅机的运行特性。本文重点分析330MW机组给水泵各种驱动方式的特点和经济性,说明当今国产330MW火电机组给水泵采用小汽机驱动能够有效降低生产厂用电率,增加上网电量,从而降低企业供电成本。最后以达拉特发电厂厂用电改造为实例,验证循环泵,凝泵的变频改造和给水泵小汽机改造的节能效果。循环泵,凝泵采用变频调速调节后,发电厂用电率平均降低了1%,电动给水泵改汽动给水泵后使厂用电率降低2.5%左右,节能效果非常明显。This paper has darat power plants, for example, analysis of the thermal power plant use of electricity, the role and composition, is indicative of a direct impact on power plants in electricity rates are fans, pumps and other large-capacity auxiliary operating characteristics. This article analyzes a variety of 330MW generating units to the pump-driven approach of the characteristics and economics shows that today's domestic 330MW thermal power unit to the pump using a small steam turbine-driven power plants can effectively reduce the production the rate of increase in Internet capacity, thereby reducing the cost of electricity companies. Finally,in order to darat electricity power plant transformation as an example, validation circulating pump, condensate pump to pump frequency transformation and transformation of a small steam turbine energy-saving effect. Circulating pumps, condensate pumps with variable frequency speed regulation, the power plants in electricity rates an average of 1%, the electric feed water pump to pump steam-driven changes have enabled us to reduce the plant power consumption rate of 2.5%, energy-saving effect is very marked.
