Statistical estimation processing method for reliability indexes of transmission system

Abstract

The invention relates to a statistical estimation processing method for reliability indexes of a transmission system, which comprises the steps of: 1, managing plant unit account and power grid topological relation by a power grid basis information management module, transmitting the plant unit account and the power grid topological relation to a transmission system basis data maintenance module,sending the power grid topological relation to a transmission system power failure analysis module; 2, generating a transmission system list by the transmission system basis data maintenance module according to power grid basis information; 3, comprehensively generating a power failure transmission system list according to power grid topology, switch deflection information, plan / failure information and transmission system information by the transmission system power failure analysis module; 4, complementing power failure events and event attributes relevant to reliability index analysis by a transmission system power failure event maintenance module and outputting the power failure events and the event attributes to a transmission system reliability statistical analysis module; and 5, synthesizing the transmission system list and the power failure transmission system list by the transmission system reliability statistical analysis module to obtain a transmission system reliability analysis result.

Description

Technical field [0001] The invention relates to a statistical processing system for the reliability index of a power transmission system, in particular to a method for evaluating and analyzing the reliability index of a power transmission system. Background technique [0002] In the past ten years, my country has made many achievements in power reliability management, but in practice, there are still the following main problems: [0003] 1) The Power Reliability Management Center releases a large number of equipment and power supply system reliability statistics data every year, but these data have not yet fully played their due role, and the depth of reliability index analysis is not enough, and it is not able to well dig equipment, In-depth issues such as management and personnel quality. [0004] 2) There is still a certain gap between the formulation of reliability standards and the development of forms. At present, my country's power industry has basically completed the separa...

AI Technical Summary

Problems solved by technology

[0003] 1) The Power Reliability Management Center publishes a large number of statistical data on the reliability of equipment and power supply systems every year, but these data have not fully played their due role, and the depth of analysis of reliability indicators is not enough. In-depth issues such as management and personnel quality

[0004] 2) There is still a certain gap between the formulation of reliability standards and the development of forms

At present, my country's power industry has basically completed the separation of power plants and power grids, and has begun pilot work on regional power markets. The original regulations can no longer fully describe the development law of my country's power supply reliability, and new indicators and management measures need to be established.

[0005] 3) Insufficient transformation and application of existing reliability research results

Inadequately combine the research results of scientific research institutes and colleges and universities with the application of electric power enterprises

[0006] 4) Due to the unbalanced level of regional economic development, the power grid level is uneven, and the management level of power supply companies is also good and bad, but the statistical indicators reported to the Power Reliability Management Center do not reflect this problem well. Some even deviate from the objective reality. Many power supply companies one-sidedly pursue indicators and use indicators for indicators, ignoring the authenticity, accuracy and completeness of reliability data.

[0007] 5) At present, there is no method and statistical evaluation device for statistics and evaluation of transmission system reliability indicators in China

The existing reliability management methods for power transmission and transformation facilities only focus on reliability management of equipment, and lack of evaluation and grasp of the overall power transmission system, which makes it difficult to coordinate the current reliability management work with asset life cycle management
