8-1 Abstract

To cooperate with the overall project of the smart grid plan, we continue promoting the feeder automation projects of the distribution system, with the goal of gradually including all users into the automated feeder, further improving the automation benefits of distribution feeders and increasing the reliability of power supply. The department of Distribution has continued to strengthen the handling and rolling review of the following aspects.

8-2 The Planning and Design

• Speed up the deployment of automatic line switches and include monitoring:
  Continue to actively deploy and review the number of automatic circuit switches to be monitored each year to comprehensively improve the automatic distribution rate of feeders across the country. It is expected to achieve full(100%) automation of distribution feeders in 2025. It can effectively reduce the scope of accidental power outages and reducing user power outage time and improving power supply quality by quickly isolating the fault interval and upstream and downstream power restoration by the system.
• Installation of automatic circuit breakers on divergent small loops:
  In addition to the deployment of automatic circuit switches on distribution feeder trunks, the implementation of the installation of automatic circuit switches on divergent small loops in metropolitan areas such as Taipei, Taichung, and Kaohsiung is included and monitored. Depending on the automation benefits of the divergent small loops implemented in the metropolitan area, the deployment area will be expanded to reduce the power outage range and time for resumption of divergent lines.

8-3 Engineering Management

• Accelerated completion of bidding announcements:
  We claim the branch office that handles the annual project of feeder automation shall complete the bidding announcement before the end of the previous year and including the time of the project bidding announcement into the operation performance index scoring items of each branch business office.

• Regularly fill in the progress of management and control tracking:
  The branch office regularly fills in reports such as “Bi-weekly Management Report before Signing the Contract”, “Monthly Report on Construction and Management of Distribution Feeder Automation Engineering” and “Monthly Report on Implementation of Control and Management of Distribution Feeder Automation Project” to facilitate tracking and manage.

• Keep tracking and control of cooperative projects:
  When coordination projects and pre-operations are hindered or delayed, a coordination meeting or other ways would be held to notify relevant departments to assist the branch office.

8-4 Conclusion

Statistics until 2023, the department of Distribution has deployed 9,045 automated feeders, and accounting for 90% of the total feeders. The proportion of “Number of accidents with downstream power restoration within 5 minutes ” in 2023 accounted for 57%, it accelerates the accident recovery time significantly.

Compared to traditional field operations, 101,456 times of automatic line switch operations at work are performed remotely. And saving 33,819 hours of manual operation time. Reducing the time for personnel to operate equipment on site. Furthermore, it can improve the safety of personnel at work.
