Embodiment

[0037] A certain type of 300MW thermal power generating unit with steam parameters of 16.7MP / 538℃ / 538℃ has been put into operation for 6 years. use figure 1 Availability prediction system of the shown thermal power generation unit and image 3 The computer software for forecasting the availability of thermal power generation units is shown, running on the computer in the control center of the power generation company. For the availability prediction of this type of 300MW thermal power unit, use figure 2 The flow chart of the availability prediction of the thermal power generation unit is shown, and the availability prediction result of this type of 300MW thermal power generation unit is obtained.

[0038] Step 1: Input the equivalent availability factor EAF(t i ) are 0.8210, 0.8686, 0.8704, 0.8943, 0.9050, 0.9143 respectively; the planned outage coefficient POF(t i ) are 0.1141, 0.0877, 0.0982, 0.0830, 0.0760, 0.0704;

[0039] Second step: Utilize the availability predic...

Abstract

The invention relates to a usability forecasting system of a thermal power generating unit, which is characterized in that a database server, a calculation server, a web page server and a user end browser are included; a usability forecasting method of the thermal power generating unit comprises the following steps: usability history data of the thermal power generating unit is counted; a usability database of the thermal power generating unit is built up; the statistical value of an equivalent available coefficient EAP (ti) which takes out planned outage is calculated; a computation module and an undetermined parameter of an equivalent available coefficient EAP (t) which takes out planned outage is determined; the planned outage times POF (t) of the thermal power generating unit is calculated; the equivalent available coefficient EAP (t) of the thermal power generating unit is predicted; the evaluation basis values that are EAF Alpha and EAF Beta of the equivalent available coefficient are determined; the quantitative evaluation of the thermal power generating unit usability is determined. The usability forecasting system has the advantages that the equivalent available coefficient of the thermal power generating unit can be quantitative-predicted, and the computer on-line quantitative evaluation of the thermal power generating unit usability is realized.

Description

technical field [0001] The invention relates to a method and system for predicting the availability of thermal power generating sets, which are applied to the quantitative prediction and quantitative evaluation of the availability of thermal power generating sets, and belong to the technical field of thermal power engineering and generating sets. Background technique [0002] In the assessment method of thermal power generating set up to standard and first-class, the equivalent availability factor EAF is used to evaluate the availability of thermal power generating set. In the use stage, the statistical results of the equivalent availability coefficient of thermal power generating units can be determined by statistically analyzing the operating history data of thermal generating units. Since 1994, the power industry has held a press conference every year to announce the statistical results of the availability of domestic thermal power generating units. After the plant netwo...
