Problems solved by technology
The conventional comprehensive power consumption rate calculation method of power generation enterprises only calculates the recorded generator power and on-grid power, without considering the impact of measurement uncertainty on the recorded values, which will bring certain challenges to the benchmarking management of power generation companies. influences
Different accuracy grades of electric energy meters, different ambient temperatures and other factors will bring certain errors to the recorded electricity.

Embodiment Construction
[0035] The present invention is described in further detail below in conjunction with accompanying drawing:
[0036] refer to figure 1 and figure 2 ,in, figure 2 M in is the gateway electric energy meter, figure 2 N in is the generator watt-hour meter, and the statistical method for the comprehensive power consumption rate of the present invention comprises the following steps:
[0037] 1) Preparing for comprehensive power consumption rate statistics;
[0038] 2) Evaluate the measurement uncertainty of the expressed value of the electrical energy of the generator;
[0039] 3) Determine whether the measurement uncertainty of the generator watt-hour meter is brought into the power generation of the generator watt-hour meter. When the measurement uncertainty of the generator watt-hour meter is brought into the recorded power generation of the generator watt-hour meter, go to Step 4), otherwise, go to step 5);
[0040] 4) Correct the generating capacity of the recorded ge...

The invention discloses a comprehensive station service power consumption rate statistical method. The method comprises the following steps: 1) performing preparation work; 2) carrying out measurementuncertainty evaluation on the electric energy representation value of the generator; 3) when the measurement uncertainty of the generator electric energy meter is brought into the recorded generatingcapacity of the generator electric energy meter, turning to the step 4), otherwise, turning to the step 5); 4) correcting the recorded generating capacity of the generator electric energy meter, andthen turning to the step 5); 5) recording the generating capacity of the generator electric energy meter in a statistical period; 6) carrying out measurement uncertainty evaluation on the gateway electric energy representation value; 7) when the gateway electric energy meter measurement uncertainty is brought into the power generation amount of the gateway electric energy meter, turning to the step 8), otherwise, turning to the step 9); 8) correcting the recorded power generation amount of the gateway electric energy meter, 9) recording the power generation amount of the gateway electric energy meter in a statistical period, and 10) calculating the comprehensive station service power consumption rate.
Description
technical field [0001] The invention belongs to the technical field of electric measurement and measurement, and relates to a statistical method for a comprehensive plant power consumption rate. Background technique [0002] In recent years, with the rapid development of my country's electric power industry, large-capacity and high-parameter generator sets have been put into operation continuously, and the modernization level of power plants has been increasing. Therefore, higher requirements have been put forward for the accuracy and consistency of electrical measurement and measurement. As various power generation groups pay more and more attention to energy saving and consumption reduction and benchmarking management, the comprehensive plant power consumption rate, as an important technical and economic indicator of generating units, has received more and more attention. [0003] When each generating set conducts benchmarking management of comprehensive plant power consum...
