[0027] According to the applicant's research, it is found that in the existing power system, the system for monitoring power equipment at key nodes of the power grid and monitoring data collection and transmission is the power grid wide-area monitoring system (WAMS). The power grid wide-area monitoring system uses synchronous phase angle measurement Technology, through the gradual layout of the synchronous phase angle measurement unit (PMU) at the key measurement points of the entire network, the real-time high-speed collection of the synchronous phase angle of the entire network and the main data of the power grid is realized. The collected data is transmitted to the wide-area monitoring master station system in real time through the power dispatching data network, so as to provide real-time monitoring, analysis and calculation of the normal operation of the power grid and accident disturbances, and obtain and grasp the dynamic process of the power grid operation in a timely ma...

[0036] In order to cooperate with the power grid monitoring system 10 provided in the first embodiment of the present invention to achieve better power grid monitoring effect, the second embodiment of the present invention also provides a grid monitoring method based on the Beidou navigation system.

[0037] Please refer to image 3 , image 3 It is a schematic flowchart of a grid monitoring method provided in the second embodiment of the present invention. The specific steps of the grid monitoring method can be as follows:

[0038] Step S21: Determine that the transmission of the monitoring data of the grid equipment to the monitoring center via the first Ethernet communication module fails within the first preset period.

[0039] Step S22: Obtain the location information and current time information of the power grid equipment through the first Beidou communication module.

[0040] Step S23: judging whether the first Beidou communication module can communicate with the mo...

Abstract

The invention provides a power grid monitoring system and method based on a Beidou navigation system, and relates to the technical field of power system online monitoring. The power grid monitoring system comprises a measurement unit and a monitoring center; the measurement unit comprises a first Beidou communication module, a first Ethernet communication module and a monitoring device; and the monitoring center comprises a central processing unit, a second Beidou communication module and a second Ethernet communication module. According to the power grid monitoring method, when transmission of monitoring data to the monitoring center by the first Ethernet communication module is failed, position information of power grid equipment and current time information are acquired by the first Beidou communication module, and after the monitoring data, the position information and the current time information are packaged into a data packet, the data packet is sent to the monitoring center bya Beidou short message communication system. According to the power grid monitoring system and method, the monitoring data is transmitted by the Beidou short message communication system so as to avoid a case that when Ethernet has a fault, the monitoring center cannot acquire the monitoring data, and improve transmission stability of the monitoring data of a power grid and safety of the power grid.

Description

technical field [0001] The invention relates to the technical field of on-line monitoring of electric power systems, in particular to a grid monitoring system and method based on the Beidou navigation system. Background technique [0002] With the popularization of electronic equipment, people have higher and higher demands on the stability and coverage of power supply, and the construction scale of the power grid is rapidly expanding. Therefore, the difficulty of monitoring the status of each power grid equipment in the power grid has also increased sharply. The problem of difficulty in obtaining monitoring data of grid equipment status, especially in areas with inconvenient transportation or lack of staff, the status of grid equipment cannot be obtained through the internal LAN of the power system, or even when the grid equipment fails to supply power, it will affect the overall power supply of the grid. The regulation and repair of power equipment will cause huge obstacle...
