Embodiment Construction

[0019] The present invention will be described in detail below.

[0020] The invention provides a data deepening analysis method of a voltage monitoring management system, which includes the following steps: the first step: collecting voltage data and measuring point classification data of each voltage category, and making voltage measuring point categories and monitoring point types Display the corresponding indicator graphics and data reports of the voltage monitoring day, month and year data, such as figure 1 shown.

[0021] The voltage category is divided into four categories, namely, A-type voltage, B-type voltage, C-type voltage and D-type voltage. The A-type voltage is a 10 (6) kV busbar of a substation with regional power supply load voltage; the Class B voltage is 35 (66) kilovolt dedicated line power supply and the user end voltage of 110 kilovolt and above power supply; the Class C voltage is 35 (66) kilovolt non-dedicated line power supply and 10 (6) kilovolt The...

Abstract

The invention relates to the field of voltage data measurement methods, and provides a voltage monitoring and management system data deepening analysis method comprising the following steps that the corresponding index analysis diagram of the voltage detection data and the data list are displayed according to the type of the voltage monitoring point and the voltage grade; different types of voltage monitoring data are acquired and displayed; the unqualified voltage data discovered in acquisition are marked and listed to the abnormal data series; and the qualified voltage rate is calculated according to the specific value of the qualified voltage data to the total voltage data. According to the method, inquiring and statistics of the voltage situation of different voltage grades and different regions can be realized and the line or the transformer area of which the qualified voltage rate is not up to the standard is alarmed. According to the method, inquiring and statistics of the situation of different voltage grades and different regions can be realized and the measuring points of which the qualified voltage rate is not up to the standard are alarmed so that the voltage situationof all the lines and the transformers areas of the power grid can be comprehensively monitored.

Description

technical field [0001] The invention relates to a method for measuring voltage data, in particular to a method for in-depth analysis of voltage pass rate. Background technique [0002] The voltage quality of the power supply system is good or bad. It is directly related to whether the power supply system can operate safely and whether users can use electricity safely. The domestic research on voltage quality monitoring system started relatively late, and the monitoring software has the shortcomings of single function, poor real-time performance of automatic graphics, and insufficient big data processing and analysis capabilities in terms of functions. Query and count the situation in the area, and give an alarm to the measuring points whose voltage qualification rate does not meet the standard, and comprehensively monitor the voltage situation of each line and station area of ​​the power grid. Contents of the invention [0003] Technical problems to be solved: [0004] ...
