Optimal Operation Of The Coal-fired Power Plant Turbine Auxiliary Machinery Research

Steam turbine thermal power plant is an effidient organic whole,operation process is quite complex,need a series of auxiliary to run,the optimal operation of the steam turbine auxiliary equipment directly related to the normal operation of generating units,connected with the power plant economic and social benefits.Thus,optimal operation of thermal power plant turbine auxiliary carries on the brief analysis has great pracitical significance and theoretical significance. Power plant water use cost is increasing, the rational transformation of frequency conversion equipment is needed to achieve the effect of saving energy and reducing consumption.With the progress of science and technology, in the future modification can be done using the inverter with pressure transmitter to maintain constant pressure water supply to be able to handle industrial water pressure problem.Need to combined with the actual situation, in the process of frequency conversion transformation to make good reform measures to adjust the running situation of thermal power plants. For large capacity units, especially to optimize the performance of the unit cold end, can greatly reduce the coal consumption, thus to achieve the goal of saving energy and reducing consumption. The purpose of this paper is to study the transformation of the cycle water pump frequency conversion of unit 1# and unit 2# and the peak cooling system of unit 5# and unit 6# in Huaneng Power Plant.Because of the “energy conservation,improve the efficiency of energy problem”has been concerned by the society,for the energy saving auxiliary steam turbine power plant in operation and improve the efficiency is the main problem of this study.
