Embodiment Construction

[0023] The invention will be further described below with reference to the accompanying drawings and in combination with specific embodiments, so that those skilled in the art can implement it by referring to the description, and the protection scope of the present invention is not limited to the specific embodiments.

[0024] The invention relates to a method for real-time monitoring of the power supply voltage of the power grid, such as figure 1 shown, including the following steps:

[0025] (1) Obtain different split-phase voltages according to the electric energy meters of different specifications;

[0026] (2) According to the obtained phase-splitting voltage, it is judged in real time whether there is a certain phase-splitting voltage less than C;

[0027] (3), if there is a certain split-phase voltage less than C, start timing, and enter step (4), otherwise enter step (5);

[0028] (4), such as figure 2 As shown, if the duration of the split-phase voltage less than ...

Abstract

The invention relates to a method for carrying out real-time monitoring on power grid supply voltage. The method is characterized by, obtaining different split-phase voltages through different specifications of electric energy meters; according to the obtained split-phase voltages, judging whether there is some split-phase voltage smaller than C in real time; and if there is some split-phase voltage smaller than C, and no long voltage event occurs, starting timing, and judging a long voltage event occurs or a short voltage event occurs. The method for carrying out real-time monitoring on the power grid supply voltage can record the quality of the actual grid voltage, effectively monitor transmission quality of the grid voltage, and can provide reliable and effective data for the electricity bureau to analyze the occurrence and ending time of long and short voltages and to take effective measures to ensure electricity consumption stability of users, thereby improving user experience.

Description

technical field [0001] The invention relates to the technical field of the national grid, in particular to a method for real-time monitoring of the power supply voltage of the grid. Background technique [0002] In the process of grid power supply, the peak period of power consumption may cause the power supply voltage in some areas to be lower than normal operation, and low voltage operation will have an impact on the service life of household appliances. In order to ensure the normal power consumption of users, it is necessary to monitor the power supply voltage of the power grid in real time, so that the power supply company can analyze and adjust the quality of the power grid. [0003] In the existing technical solutions, only records are made for the absolute power-off situation, that is, the electric energy meter does not work as a power-off, and works as a power-on, lacking the recording and feedback of the actual grid voltage quality.
