Calculation method, equipment and medium for inaccurate rate of on-line monitoring station area

Abstract

The invention discloses a calculation method, equipment and medium for online monitoring of misalignment rate of a station area, which comprises the steps of: step S1, online acquisition of time-point power data of each user meter under the station area master meter; step S2, verification Whether the obtained total meter power data of the station area is 0, if the total meter power data of the station area is 0, it is determined that the station area is not in use or the master meter is faulty, and if the total meter power data of the station area is not 0, further calculation is performed; step S3 , according to the data obtained online, use the prototype flow conservation formula of the electric energy meter error rate model to calculate the error rate of each user's meter, the line loss rate of the station area, and the fixed loss of the station area; step S4, use the correction model to calculate the error rate of the total meter, And correct the error rate of each user's meter, the line loss rate of the station area, and the fixed loss of the station area. By implementing the present invention, the inaccuracy rate of the intelligent electric meter is monitored and calculated on-line, so that the consideration factors for the calculation of the inaccuracy rate are enriched, the output of the result quantity is increased, and the result is more credible and accurate.

Description

technical field [0001] The invention belongs to the field of information technology, and relates to a calculation method, equipment and media for the misalignment rate of an online monitoring station area. Background technique [0002] With the further popularization of smart meters, grid data has been further enriched and expanded in terms of quantity and timeliness, especially the online monitoring data of equipment has been further enriched, providing data support for online monitoring of metering asset status. The full life cycle of metering equipment covers all stages from procurement and delivery management, equipment acceptance management, verification and testing management, warehousing and distribution management, equipment installation management, equipment operation management, equipment dismantling management to final asset scrap management. Among them, the power grid mainly includes the following processes in the operation and management process of smart meters:...

Problems solved by technology

However, the actual operating life of electric energy meters can generally reach 10 to 15 years, and the quality level of electric energy meters on the grid can be effectively monitored, so the "one size fits all" expiration rotation mechanism is unreasonable, and the number of electric energy meters that pass the verification and are scrapped in advance is huge. It is not conducive to energy saving and environmental protection, and wastes social resources. At the same time, changing the meter will cause the old dismantling, new purchase and installation, etc., resulting in a huge waste of manpower and material resources.
