Embodiment Construction

[0024] The specific implementation manner of the present invention will be described in further detail below according to the accompanying drawings.

[0025] The invention provides a regional power grid transient overvoltage monitoring system, the system structure diagram is as follows figure 1 shown by figure 1 It can be seen that the system includes: a transient voltage monitoring device, a host computer in a substation and an overvoltage monitoring application server.

[0026] The transient voltage monitoring device is connected to the bus, including a sampling channel module and a transmission module. The transient voltage monitoring device starts recording when the voltage waveform changes significantly, and compresses similar data, and uploads the compressed transient voltage data to the upper computer in the substation through Ethernet.

[0027] In order to accurately capture the maximum value of the rapidly changing pulse voltage, it must be collected with the highes...

Abstract

The invention provides a regional power grid transient overvoltage monitoring system, comprising: a transient voltage monitoring device connected to the bus, including a sampling channel module and a transmission module; the transient voltage monitoring device starts recording when the voltage waveform changes significantly, and Compress the data with similar points, and upload the compressed transient voltage data to the host computer in the substation through Ethernet; Read and set the parameters of the transient voltage monitoring device, receive and store the transient voltage data uploaded by the transient voltage monitoring device, and regularly update the data to the overvoltage monitoring application server through Ethernet. In the system provided by the invention, the monitoring data is uploaded layer by layer, so that the user can view and analyze the overvoltage monitoring situation of each substation without going to the substation.

Description

technical field [0001] The invention relates to the field of regional power grid fault monitoring, in particular to a regional power grid transient overvoltage monitoring system. Background technique [0002] The monitoring and recording of voltage in the substation can provide reliable and accurate information for analyzing the impact of overvoltage on the power grid during the occurrence and development process. [0003] In most overvoltage monitoring methods, overvoltage monitoring only monitors the overvoltage in a certain substation, and the recording time is short and the sampling rate is low, which is difficult to meet the monitoring of various overvoltages in the regional power grid. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides a regional power grid transient overvoltage monitoring system, the system comprising: a transient voltage monitoring device, a host computer in a substation and an overvoltage...
