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

Disclosed is a calculation method for a real-time electricity classified load of a power system distribution transformer terminal. The calculation method comprises an S1 step of collecting real-time telemetry data of all power distribution terminals in an area every 15 minutes; an S2 step of storing the real-time telemetry data into a high-speed timing sequence database; an S3 step of doing statistics of the total electricity sale quantity Wp of a power distribution terminal in the last month, various electricity utilization class information and the power sale quantity of all users in the last month; an S4 step of obtaining the total electricity sale quantity of all electricity utilization classes of the power distribution terminal; an S5 step of obtaining the proportion of electricity sale of an electricity utilization class in the last month; an S6 step of reading out real-time electricity utilization classified loads; and an S7 step of accumulating to obtain the total classified load condition in the area. According to the invention, basic load data can be collected remotely in real time at present, the real-time electricity utilization classified load condition in the area can be calculated by using a specific method, and analysis of the real-time electricity classified load condition is facilitated for a power sector.

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...
