Method and device for testing water balance of thermal power plant

Abstract

The invention provides a thermal power plant water balance testing method and device. The method comprises the steps that water balance physical quantity initial parameters such as water supply, water drainage, water consumption, unit parameters and production environment parameters of all subsystems obtained in advance are input into an intelligent water balance management system; the intelligent water balance management system carries out data processing on a water balance physical quantity according to a set model; after data processing, water balance physical quantity statistical parameters such as water consumption and water drainage of each subsystem and the whole plant and a water balance statistical report are automatically generated; and the water balance physical quantity statistical parameters is compared with standard water balance physical quantity statistical parameters or empirical values of units of the same type to obtain the water consumption level grade of the whole plant in a certain production period of the power plant, and optimization suggestions is generated for improving the water consumption level grade.

Description

technical field [0001] The application relates to the field of water balance testing of thermal power plants, in particular to a method and device for testing water balance of thermal power plants. Background technique [0002] The water balance test of thermal power plants usually uses a power plant as a water system to study the balance relationship between water input, output and loss, which is the basis for thermal power plants to strengthen scientific water management, promote rational water use, and save water and reduce emissions. By observing the intake, use, drainage, water consumption and water quality, we can grasp the water consumption, drainage and unreasonable water consumption of each system in the power plant, tap the water-saving potential, formulate water-saving measures, and make the thermal power plant realize scientific water use. [0003] At present, the water system management and control of most thermal power plants are operated independently and dece...

Problems solved by technology

The existing water-saving measures are not suitable for the current production and operation conditions, resulting in a disconnect between local water-saving management policies and actual production, and the water-saving effect of the whole plant is not ideal

[0004] At present, there is no uniform, complete and feasible water balance test specification and method for thermal power plants. Relevant policies only provide principled regulations on water balance test, and the determination of the crucial water system division, measurement point and measurement period And the statistical rules of the measurement results have not been described and stipulated in detail, resulting in strong human factors in the water balance test results, lack of representativeness, and it is difficult to play its due role

Moreover, after completing the water balance test work, complex calculations and cumbersome statistics must be performed on the test results, which also requires a lot of time and energy.
