A multi-station unified verification and acceptance method for power system monitoring signals

Abstract

The present invention discloses an electric power system monitoring signal multi-station uniform checking and accepting method. The method comprises the steps of reading a checking and accepting card, constructing a temporary database to receive the point table information uploaded by a regulation and control system, analyzing and comparing the information of the checking and accepting card and the point table information, determining whether the information of the checking and accepting card and the point table information are consistent, if the information of the checking and accepting card and the point table information are inconsistent, modifying the point table information of the regulation and control system, reanalyzing, otherwise taking the information of the checking and accepting card as the standard checking and accepting information to import to the regulation and control system; receiving the standard checking and accepting information, determining a to-be-checked and accepted station, real-timely reading the standard checking and accepting information, determining a to-be-checked and accepted measurement point, circularly receiving the alarm direct transmission signals reported by the measurement point, comparing the reported signals and the standard checking and accepting information, determining whether the format and the sequence match, if the format and the sequence match, checking and accepting the measurement point, otherwise, prompting the errors. According to the present invention, the information of a power substation can be checked and accepted automatically.

Description

Technical field [0001] The invention relates to a multi-station unified check and acceptance method for power system monitoring signals. Background technique [0002] With the continuous expansion of smart grids, a large number of new substations have been invested, and these new substations need to check various monitoring information. [0003] The current substation access acceptance mainly relies on manpower. The monitoring information access acceptance mode is: after the on-site equipment installation is completed, the commissioning is completed, and the communication conditions are complete, the acceptance is carried out with the main station, and the information is checked with the on-site maintenance personnel through a direct telephone. The construction of the communication link required for acceptance is lagging, resulting in tight acceptance time and heavy tasks. In order to ensure the completion of the task, they often work overtime. At the same time, due to the need to ...

AI Technical Summary

Problems solved by technology

[0005] (1) In order to ensure the normal development of daily work, 2-3 people on duty must be guaranteed for each duty, and the management tasks of the dispatching agency are heavy, and the professionalism of new employees is not solid enough. For each acceptance check, 2 key personnel are transferred to carry out the acceptance check of the long day shift. The development of normal monitoring business has caused a great burden. Later, with the expansion of the power grid structure, the acceptance work will be more arduous, and because the commissioning requires personnel from both parties to be online at the same time, it will involve a lot of manpower and material resources

[0006] (2) The construction of the communication channel link relied on for information acceptance is lagging behind, and can only be constructed after the transmission line is disconnected, and the disconnection time of the line is short, and the remaining time for acceptance is tight

If wireless transmission is used, the problem of signal instability is prone to occur, and it does not meet the relevant requirements of the "Regulations on Safety Protection of Electric Power Monitoring System"

[0007] (3) The acceptance process is not perfect

During the period, the substation and the main station were checking and accepting while debugging. When problems were discovered and rectified, the other party had to suspend the acceptance work and wait for the defect processing to be completed, which wasted a lot of time. At the same time, the remote control acceptance could only be carried out after the fiber channel was established;

[0008] (4) It is impossible to operate the original data. The current information database of the acceptance data has a large amount of information. If it is used for acceptance, the speed is slow, the workload is heavy, and the original database is easy to be damaged, resulting in serious situations such as data loss.
