Embodiment Construction

[0023] Below, the present invention will be further described in conjunction with accompanying drawing:

[0024] A preferred embodiment of the calculation method for the real-time power consumption classification load of the power system distribution transformer terminal of the present invention includes the following steps:

[0025] S1 obtains all distribution transformer terminal information in a certain region in the marketing system, for example, there are 4 distribution transformer terminals A, B, C, and D in a certain region;

[0026] The S2 metering master station collects real-time telemetry data of all distribution transformer terminals in a certain area through wireless GPRS every 15 minutes: including active power, reactive power, voltage, current and power factor;

[0027] S3 transfers the real-time loads of all 4 distribution transformers (P a ,P b ,P c ,P d ) Telemetry data is stored in a high-speed time-series database;

[0028] S4 reads all electricity con...

Abstract

A calculation method for real-time power consumption classification load of power system distribution transformer terminals: S1 collects real-time telemetry data of all distribution transformer terminals in a certain area every 15 minutes; S2 stores real-time telemetry data in a high-speed time series database; S3 counts a certain distribution transformer terminal The total electricity sales Wp of last month, the information of each electricity consumption category, and the electricity sales of all users in the previous month; S4 calculates the sum of electricity sales of all electricity consumption categories under a certain distribution transformer terminal; S5 calculates a certain electricity consumption The historical power sales ratio of the last month of the category; S6 reads the corresponding real-time load P of the distribution transformer terminal in the time series database r Multiplied by the power consumption ratio of all power consumption category users of the distribution transformer terminal last month, the real-time power consumption classification load is obtained; S7 accumulates to obtain the regional general classification load situation. The invention utilizes the basic load data which can be collected in real time from a remote place at present, and calculates the real-time power consumption classification load situation of the region by a specific method, so as to facilitate the power department to analyze the real-time power consumption classification load situation.

Description

technical field [0001] The invention relates to a method for calculating the classification load of power consumption of a distribution transformer terminal in a power system, in particular to a method for calculating the classification load of power consumption for a distribution transformer terminal of a power system in real time. Background technique [0002] It is one of the most common statistical items for power departments at all levels to count the power consumption classification load composition of an area or a line or even a transformer. However, the change of load is changing rapidly, so the statistics of traditional power can only be based on a long period of time. Statistical electricity (such as monthly electricity) cannot provide real-time data with reference significance, that is, it is impossible to calculate real-time power consumption classification load. [0003] According to the traditional method, to calculate the real-time power consumption classifica...
