Embodiment 1

[0053] Combine below Figure 1-2 To further describe the present invention.

[0054] The present invention adopts the following technical scheme: a distributed measuring line loss and monitoring power grid equipment, characterized in that it includes a main server 1, at least one secondary server 2 connected to the main server 1 and at least one secondary server 2 Connected tertiary server 3;

[0055] The tertiary server 3 is connected to at least one external user terminal;

[0056] Described tertiary server 3 comprises collection chip 31, tertiary measurement module 32, tertiary memory 33, tertiary processing module 34 and tertiary communication module 35;

[0057] The acquisition chip 31 is connected with a third-level processing module 34;

[0058] The tertiary metering module 32 is connected with the tertiary processing module 34;

[0059] The third-level processing module 34 processes the data delivered by the acquisition chip 31 and the data delivered by the third-l...

Embodiment 2

[0091] In the actual work process, if the data is continuously collected, the workload of the servers at all levels is too large, which does not meet the actual work needs. Therefore, it is necessary to set an appropriate acquisition and calculation frequency.

[0092] A timer C36 is arranged on the third-level server 3, and the timer C36 is connected with the acquisition chip 31 and the third-level metering module 32;

[0093]The function of the timer C36 is to send instructions to the acquisition chip 31 and the third-level metering module 32 after each time period, and after receiving the instructions, the acquisition chip 31 and the third-level metering module 32 start to work, while the remaining modules of the third-level server 3 Work together, stop after completing a job, and wait for the timer C36 to send the next command. The secondary metering module 21 of the timer B25 is connected, and the timer B25 sends instructions to the secondary metering module 21 after eac...

Embodiment 3

[0096] The monitoring module 14 of the present invention stores preset data and can receive external information.

[0097] The line loss values ​​calculated by servers at all levels will eventually pass through the monitoring module 14, and the monitoring module 14 will compare the actual calculated line loss values ​​with the preset data. The calculated line loss value is a normal value. If the actual calculated line loss value exceeds the allowable range of the preset data, it is considered that the line loss value is abnormal.

[0098] When an abnormal line loss value is found, the monitoring module 14 sends a warning message, and the abnormal area can be quickly determined by determining the area where the server sending the abnormal line loss value is located. Maintenance personnel can quickly rush to the maintenance site when they receive the maintenance notice, instead of needing to check in a certain area to determine the maintenance site as it is now. The denser the...

Abstract

The invention discloses a distributed line loss determination and power grid monitoring equipment and method. The equipment comprises a main server, at least one second-level server connected with the main server and at least one third-level server connected with the second-level server, wherein the third-level server is at least connected with an external user terminal, the third-level server comprises an acquisition chip, a third-level metering module, a third-level memory, a third-level processing module and a third-level communication module, the second-level server comprises a second-level metering module, a second-level processing module, a second-level communication module and a second-level memory, and the main server comprises a communication module, a metering module, an analysis module, a monitoring module and a main memory. Data of the power grid can be conveniently acquired through three-level design, a line loss value can be acquired through calculation on the basis of the acquired data, the data is accurate, calculation is rapid, an abnormal data area can be found out through comparing an actual line loss value and a theoretical line loss value, an overhaul and maintenance instruction can be timely emitted, and power grid operation stability is improved.

Description

technical field [0001] The invention relates to the field of power transmission system analysis, in particular to a device and method for distributed line loss measurement and power grid monitoring. Background technique [0002] The power system is an electric energy production and consumption system composed of power plants, power transmission and transformation lines, power supply and distribution stations, and power consumption. Its function is to convert the primary energy in nature into electric energy through the power generation device, and then supply the electric energy to various users through power transmission, transformation and distribution. [0003] The power grid is one of the concrete manifestations of the power system and plays an irreplaceable role in the country's economic development. China has a vast territory. In order to achieve the largest possible coverage area, the construction of power grids is also developing rapidly. At the same time, in order...
