Energy-saving detection method of large generator set

Abstract

The invention relates to an energy-saving detection method of a large generator set. The energy-saving detection method comprises the following steps of: (1), obtaining gross electricity generation of the generator set during an operation cycle at first; (2), obtaining electricity generation according to a distribution function of generation power; (3), obtaining equivalent increment of a generation standard coal consumption rate; (4), obtaining equivalent increment of a power supply standard coal consumption rate; (5), obtaining equivalent increment of boiler efficiency; and (6), obtaining equivalent increment of a station service power consumption rate. Aiming at the disadvantage of being incapable of adapting to all load periods and all working conditions in the current energy-saving detection method, the distributed energy-saving detection method is mainly divided into two parts, namely detection of an efficiency parameter and detection of an energy consumption parameter, wherein the detection of the efficiency parameter is mainly used for evaluating efficiency parameter distribution difference of the boiler efficiency and the station service power consumption rate in all loads and all working conditions during a certain operation cycle (time, day, week, month, year and many years) of the generator set; the detection of the energy consumption parameter is mainly used for detecting energy consumption parameter distribution difference of generation coal consumption and power supply coal consumption in all loads and all working conditions during a certain operation cycle (time, day, week, month, year and many years) of the generator set; and whether operation of the generator set saves energy can be judged by analyzing the efficiency parameter distribution difference and the energy consumption parameter distribution difference of the generator set.

Description

technical field [0001] The invention relates to the technical field of energy saving of thermal power generating sets, in particular to an energy saving detection method for large generating sets. Background technique [0002] With the in-depth development of the power system reform of "separation of factories and grids, bidding online", the power market is becoming more and more standardized, and power production enterprises will face increasingly fierce market competition. Especially in the context of tight coal supply and rising prices in recent years, in order to reduce power generation costs, improve unit operation economy and environmental protection performance, power plants require production information sharing within the entire power plant to effectively strengthen production equipment Performance management and energy management. In this way, the management of energy saving and consumption reduction and operation optimization of the units has been put on the very...
