Optimization operational method based on energy consumption analysis for power plant and system thereof

Abstract

The invention discloses an optimization operation method based on energy consumption analysis for power plant and a system thereof. The method includes the following steps: a data acquisition subsystem acquires real-time operational data and carries out pre-processing on the specific real-time data; a data processing subsystem analyzes and calculates the real-time data, so as to obtain the real-time energy consumption index under the current working condition, the real-time energy consumption index under the current working condition is compared with the energy consumption index under the corresponding working condition stored in an optimal working condition database, comparison result is output to a data display subsystem, and meanwhile if the real-time energy consumption index obtained by calculation is superior to the optimal energy consumption index under the corresponding working condition, the current real-time working condition is stored to be corresponding optimal working condition; and the data display subsystem displays the real-time energy consumption index under the current working condition and the comparison result of optimal energy consumption indexes under the corresponding working conditions. The method of the invention can more accurately analyze various energy consumption differences of power plant and the reason of exceeding of energy consumption difference, and a reliable optimization scheme is provided.

Description

technical field [0001] The invention relates to an automatic monitoring system of a power plant, in particular to a method for optimizing operation of a power plant based on energy consumption analysis and a system thereof. Background technique [0002] The economical efficiency of thermal power plant operation is finally measured by the power supply coal consumption rate of the unit, and the coal consumption difference of the unit is an important comprehensive index to measure the economic management level of the unit or even the entire power plant. [0003] Such as figure 1 Expresses the coal consumption characteristic curve of a generating set. In the figure, curve 1' is the design coal consumption curve of the unit. The size of the unit capacity, the design of the thermal system, and the selection of thermal equipment determine the design value of the coal consumption for power supply. Curve 2' is the characteristic curve of coal consumption after the manufacturing and...

Problems solved by technology

However, under normal circumstances, there is an objective gap between the actual operating conditions of the power plant unit and the design target value, which can easily lead to unsatisfactory results of energy consumption analysis. , if it is still listed as one of the main factors affecting the controllable consumption difference b, it is easy to ignore the adjustment of other parameters, which has no practical significance for operation optimization and adjustment guidance; more often, the optimal single economic index, does not lead to the reduction of the overall energy consumption of the unit

Moreover, the design value or test value is not consistent (the load of the unit is from 30% to 100%), but only some parameters of some typical loads, and it is not comprehensive at the same time, and cannot guide the needs of the optimal operation of the continuously changing unit
