Problems solved by technology

Since the target users are not single and the scope is too wide, it is impossible to completely proceed from the actual situation of local dispatching and operation work, and centralize the functions required for dispatching.
[0004] 2. Lack of visual interface functions
The abnormal operation mode of all substations cannot be directly reflected on one interface, and the dispatcher needs to click on the substation

Embodiment Construction

[0014] figure 1 It is the main block diagram of the system, which schematically depicts the monitoring and analysis system of the power grid operation status, which includes the acquisition client 1, the terminal server 2 and the data storage 3. The acquisition client 1 obtains the reactive voltage, stability limit, 220KV main transformer N-1 status or grid abnormal status signal of the 220KV substation equipment by connecting to each grid substation equipment in an area, and connects to the terminal server 2 , the data storage 3 is connected to the terminal server 2, and further includes a data collection node 4 connected to the collection client 1, which includes a signal transceiver 41 for receiving the signal in a set area around it; A geographic information processor 42 is used to confirm the position information of the new power transformation equipment in the set area; a signal controller 43 is used to control the signals from all the power transformation equipment in t...

Abstract

The invention discloses a power grid operation state monitoring and analyzing system for a power system. The power grid operation state monitoring and analyzing system comprises an acquisition client, a terminal server, a data storage device and data acquisition nodes. Each data acquisition node comprises a signal transceiver, a geographic information processor and a signal controller, wherein the signal transceiver acquires a plurality of signals in a set area, the position information of the signals is determined through the maximum signal intensity in the geographic information processor, and the signals are processed through the signal controller and are transmitted to the acquisition client through the signal transceiver. The system has the advantages that the system is complementary with a conventional system, and functions required by scheduling are integrated; the abnormal operating mode, abnormality, early warning and other conditions of a power grid main rack can be intuitively reflected in real time through one interface; intelligent identification of a main transformer N-1, auxiliary processing functions, reactive comprehensive voltage analysis, short message alarm functions are realized; and later development and maintenance are easy. The invention also discloses a monitoring and analyzing method.

Description

technical field [0001] The present invention relates to power transmission and distribution technology of electric power system grid, more specifically, the present invention relates to a monitoring, analysis and early warning system of grid operation status. Background technique [0002] The safe and stable operation of the power grid is affected by many factors such as the operation mode of the power grid, the power flow situation, and the status of equipment. For dispatching work, how to grasp these information in a timely, intuitive and accurate manner is very important. At present, the dispatching automation systems used in the market all adopt the integrated system of prefecture, county or even province, prefecture and county, and the data server is also the same server, and the user is not only for dispatching, which has the following disadvantages: [0003] 1. Broad but not precise. Since the target users are not single and the scope is too wide, it is impossible to...
