Embodiment Construction

[0015] The following claims and summary of the present invention will be further described in detail.

[0016] 1. Calculation of qualified rate of measuring point voltage

[0017] The invention is built on a power monitoring system. Both the measuring point and the voltage data of the measuring point are taken from the database of the power monitoring system. The voltage data of the measuring point is sampled in real time at a certain time interval and stored in the real-time database of the power monitoring system. Usually, the sampling interval of these voltage data is 3-5 minutes, thus forming a sequence of voltage data. For a measuring point, its voltage qualification rate can be calculated by the formula Calculated to get. Since the voltage data of the measuring point is a sequence, each voltage value in the sequence represents the value within 3-5 minutes. Therefore, in actual calculation, the above formula can also be expressed as: .

Abstract

The invention discloses an integrated voltage qualified rate evaluation method. The integrated voltage qualified rate evaluation method comprises steps that: S1, detection points are classified into n types, and integrated voltage weighted values of each type of detection points are set; S2, statistics of a voltage qualified rate of each detection point is carried out; S3, statistics of sum of voltage qualified rates of each type of detection points is carried out; and S4, the integrated voltage qualified rate can be acquired by carrying out weighted arithmetic according to the sum of voltage qualified rates of each type of detection points and the integrated voltage weighted values. According to the method, the integrated voltage qualified rate is an average weighted value of each type of detection points, so the acquired integrated voltage qualified rate has certain emphasis, can reflect importance degrees of different detection points and can reflect different voltage qualified rate requirements of different electric lines.

Description

technical field [0001] The present invention relates to the automation of the control of power supply or distribution systems. Background technique [0002] In the power system, the comprehensive voltage qualification rate is an important indicator to reflect the power supply. Generally, the comprehensive voltage qualification rate of the grid system usually adopts the average method. In the actual power supply system, residential electricity, industrial electricity, urban electricity, rural electricity, power supply lines with different voltages, power plant and substation bus voltage, and user end power supply voltage all have different voltage qualification rates. The traditional average value method is difficult to express the requirements of different voltage qualification rates of different power consumption and different lines. Contents of the invention [0003] The problem to be solved by the present invention is to design an evaluation method for the comprehensi...
