The embodiment of the invention provides a system and method for monitoring performance of a thermal power generating unit. The system comprises a wireless collection device, a processing device and a switching device. The wireless collection device is connected with a waste-heat utilization system of the thermal power generating unit and used for collecting unit operation parameters of the waste-heat utilization system of the thermal power generating unit. The unit operation parameters comprise drive steam pressure, condensation water pressure and condensation water flow, and are sent to the processing device. The processing device sets up a characteristic vector set between the energy consumption characteristic and the unit operation parameters of the thermal power generating unit and then obtains the net coal consumption rate and the performance of the thermal power generating unit. The switching device is connected with the processing device and used for carrying out switching according to the obtained performance of the thermal power generating unit through the processing device. The wireless collection device is used for accurately collecting data in real time. The performance of the thermal power generating unit under different work conditions can be determined according to units of different types, and operation investment and switching can be reasonably arranged.
Description
technical field [0001] The invention relates to the field of thermal power generation, in particular to a monitoring system and method for the performance of a thermal power unit. Background technique [0002] With the worldwide energy shortage and the intensification of market competition, energy conservation and consumption reduction have become the main goals of various work carried out by power companies and power stations in various countries. As early as the early 1980s, EPRI of the United States conducted a comprehensive investigation and research on all coal-fired power plants in the United States, and analyzed that the adjustment research of unit operation mode has considerable energy-saving potential. [0003] Saving energy and reducing energy consumption is also a long-term basic national policy of our country. Power plants are large energy consumers that consume primary energy and produce secondary energy. The annual coal consumption accounts for one-half of the...
