Coastal Grid Substations Unattended Transformation

Shengli Oilfield BingHai power company management many power substaion, resulting in lack of run production staff members, staff time to run over labor law requirements, health and safety of workers to run cause some potential impact. To address the shortage of workers and reduce labor intensity, the unmanned-work substation is a practical way. Through the research program of unmanned-work substations, compared to various programs, the grid is optimized for unattended coastal rehabilitation programs, in particular, the applicability of the program, compatibility and management for grid applications in areas such as special research, to ensure electricity to meet the oil requirements. Planning three centralized control station, such as xingul station, dongyi station and donger station, control station in the three monitoring arrangements for staff, the other unmanned substations substation reconstruction. This control station by around three unmanned surveillance control station to address staff shortages and safe operation of such contradictions.The unmanned -work is an easy microprocessor-based protection, network communications, background monitoring and remote video technology and integrated systems, in addition to facing many on-site and practical issues, the definition of centralized control center functions, need to meet technical indicators, how to set up centralized control center, unattended substation to meet the standards, the corresponding transformation of a secondary device, communication configuration, as well as unmanned substations to establish the following how to run the management. The main innovation of the project:integration of a variety of hard and soft technologies, the use of computer protection, network communications and information processing background, collecting large amount of data, powerful and compatibility;to achieve real-time data acquisition, telemetry, remote, remote control, remote adjustment, data reporting and other functions;for a variety of harsh operating environment and reliability; dual backup, operating records, fault recording, real-time alarm and other technology to improve system reliability and achieve a real unattended. Implementation of the project has good economic and social benefits within the scope of centralized control station switching can be completed at this site, and the fault analysis and judgments, which saves labor, and reduce intermediate links. The implementation of the study greatly improved the safety of field substations, reliability, reduce attendant labor, to achieve reduced to increase efficiency and meet the requirements of power development field.
