Description

Method and system for calculating converted electric quantity of synchronous comprehensive line loss Technical Field The invention relates to the technical field of comprehensive line loss converted electric quantity calculation, in particular to a synchronous comprehensive line loss converted electric quantity calculation method and system. Background The contemporaneous comprehensive line loss is a performance index for the upper authorities of the power supply enterprises to check the loss reduction and synergy of the lower authorities, directly relates to the economic benefit of the power enterprises, and is one of the core indexes of the power enterprises. The true and accurate contemporaneous integrated line loss value is a key point for ensuring the realization of the target. The calculation formula is that the synchronous comprehensive line loss rate= (the power supply amount of the power supply bureau (bureau) -the sum of the settlement power amounts of all the power consumption users in the power supply bureau (bureau)) and the power supply amount of the power supply bureau (bureau) are 100%, wherein the power selling amount is equal to the sum of the power consumption amounts of all the power consumption users in the power supply bureau (bureau) in the synchronous line loss calculation period, and the power supply amount corresponding to the power selling amounts is the power supply amount. From the above, it is known that obtaining accurate electric power is a key. The electric quantity obtained in the current power industry is firstly obtained from a metering master station system to obtain the accurate electric quantity of a meter, and secondly, the meter which does not obtain the electric quantity accurately is calculated by calculating the balance electric quantity of marketing. The calculation formula is that the converted electric quantity= (settlement electric quantity/time span corresponding to the settlement electric quantity) is the line loss calculation time span of the synchronous comprehensive line loss. I.e. average apportionment of the amount of settlement power into each time point, which is a mean value calculation method. However, in practice, the electricity consumption of the consumers is usually not equal on each date, so that the electricity value calculated in this way has a large deviation from the actual value. For the fact that accurate electric quantity cannot be obtained is caused by service factors such as replacement, stop reporting and sales of a metering device, and the like of a meter, the deviation of converted electric quantity is influenced by the service factors in a superposition manner on the basis of the deviation. In general, various businesses need to pass through a plurality of nodes of a plurality of departments, and the recording system of business information generally lags behind the scene, so that the settlement electric quantity displayed by the marketing system may not be the electric quantity of the line loss calculation current period, or the time span corresponding to the settlement electric quantity has deviation from the actual time span, and at the moment, the deviation between the obtained converted electric quantity value and the actual value is very large according to a converted electric quantity calculation formula. In the calculation of the synchronous comprehensive line loss of which the conversion electric quantity is generally more than 8%, the adoption can overestimate or underestimate the synchronous comprehensive line loss by more than 2% in a marketing settlement electric quantity conversion calculation mode, and the deviation is 100% when the synchronous comprehensive line loss is only 2.2% similar to that of a Shenzhen power supply bureau, the actual value is seriously deviated, the synchronous comprehensive line loss level of each power supply bureau cannot be truly reflected, and the upper-level authorities of an in-plane power supply enterprise can hardly use the value as a performance assessment index for lower-level departments, so that the purposes of energy conservation, loss reduction and efficiency improvement are achieved.
