Embodiment Construction

[0062] The present invention is a control theory-based real-time measurement and assessment query system for the regulation performance of generator sets, which includes the following steps:

[0063] 1) Field data collected by SCADA system;

[0064] 2) Conduct online evaluation on the adjustment speed, response time, adjustment accuracy, adjustment capacity and other indicators of single or multiple AGC units to obtain the actual performance indicators of the unit; statistically calculate the operation rate of the AGC unit, and save the results in the relational database oracle;

[0065] 3) Develop a query system, which can flexibly and conveniently query the adjustment rate, response time, adjustment accuracy, adjustment capacity and commissioning rate of the daily and monthly AGC units, which is convenient for the power grid dispatching center to assess the units.

[0066] The specific indicators of the generator set regulation performance real-time measurement and assessme...

Abstract

The invention belongs to the technical field of power grid dispatching automation, and in particular relates to a control theory-based real-time measurement and assessment query system for the regulation performance of a generator set, which is a method for online measurement of the regulation performance of a generator set participating in automatic power generation control, and can provide Check query function. The invention can measure parameters such as adjustment rate, adjustment accuracy and response time of each AGC unit in real time on-line. Rewriting the actual parameters into the AGC unit parameter table will help control the AGC unit, reduce frequent adjustments to the generator set, reduce the loss of the generator set, improve the regional CPS index, stabilize the grid frequency, and improve the stability of the grid. It also provides credible data for AGC unit assessment.

Description

Technical field [0001] The invention belongs to the technical field of power grid dispatching automation, and in particular relates to a control theory-based real-time measurement and assessment query system for the regulation performance of a generator set, which is a method for online measurement of the regulation performance of a generator set participating in automatic power generation control, and can provide Check query function. Background technique [0002] Automatic generation control technology AGC (Automatic Generation Control) is an important technical means to balance power system power generation and load in real time, and to ensure the frequency quality and safe operation of the power system. According to the requirements of the State Electricity Regulatory Commission: thermal power units of 200,000 kilowatts and above in grid-connected power plants and non-runoff hydropower units of 40,000 kilowatts and above in grid-connected power plants should have AGC fun...
