Problems solved by technology

Most of the fault information reported by users is only the user's address information, which cannot meet the requirements of on-site repair personnel to quickly and accurately determine the faulty equipment and location
Faults discovered by the power consumption information collection system and faults recorded by on-site line patrol personnel, how to quickly locate the fault location has also become a factor that affects the progress of emergency repairs

Abstract

The invention discloses a power distribution network fault diagnosis system and method based on a CIM model. Secondary diagnosis and judgment are performed on a result of fault positioning, thus the accuracy of power distribution network fault diagnostic analysis can be further improved, and at the same time, RSA encryption and a digital signature algorithm are utilized to perform confidential treatment on data transmitted through an interface, thereby improving information security and confidentiality. Based on an IPX / SPX network high-speed transport protocol, data transmission efficiency is improved, and high efficiency of big data transmission is satisfied. Through extension of a distribution network emergency maintenance platform in a medium- and low-voltage power supply path fault, fault control is practically performed on an overall power supply path of the distribution network, thereby facilitating safety command by a regulation and control center and on-site interaction, and improving the lean level of emergency maintenance.

Description

Technical field [0001] The invention relates to a distribution network fault diagnosis system and method based on a CIM model. Background technique [0002] With the development of the economy, the rapid growth of power demand, and the continuous expansion of the scale of the power grid, the society has higher and higher requirements for the power supply reliability, power quality, and service level of the power grid. The speed of repairing power distribution network faults has become an important link that affects the reliability of power supply. [0003] The 10kV fault discovered by the distribution automation has a wide range of power outages and a large social impact. How to quickly grasp the scope of the fault and the users, and proactively notify the users of the power outage information and the current status of repairs, which can greatly reduce the number of user requests for repairs and improve customer service Level. Most of the fault information reported by users is on...
