Substation Automation

Intoroduction Tokyo Dento Company (the former foundation of TEPCO) introduced the first automation of substation supervisory control in October 1930. Since 1960s the number of substations has been increased to cope with the increasing electricity demand, and also it has become to be expected that high reliability in power supply should be realized. So that, the centralized SCADA (Supervisory Control And Data Acquisition) system featuring computers was developed, and unmanned system has been adopted mainly for the distribution substations (HV/LV substation which supplies distribution feeders).

Automation of substation supervisory control has made great contributions for the improvement of productivity, efficiency and immediate restoration of outages.

The five days training course is available for the engineers who need the engineering and experience accumulated by TEPCO through its history in the field of automation. TEPCO believes that the course would be really useful for the engineers of utilities, especially for the system planners of the automation systems.

Outline of the Course
The training course consists of five days and main subject is "automation of supervisory control" at the distribution substations. TEPCO can process its substantial experience into the useful information by the same point of view with the attendants as "engineers of utilities". It is so helpful in order to find out the most suitable system for your company.

Main Subjects are as follows:
  1. Outline of Substation Facilities in TEPCO
  2. History of Substation Supervisory Remote Control Systems in TEPCO
  3. Functions and Structures of Supervisory Remote Control Devices and Centralized SCADA Systems
  4. Supplemental Facilities supporting Supervisory Remote Control and Centralized SCADA Systems
  5. Technical Tour for Control Centers and Distribution Substations

The lectures are performed not only in classroom, but also in TEPCO‘s Training Center using the SCADA simulator. The course includes a tour to the substations and other facilities to help attendants understand the real situations and issues related to the field.

In addition, attendants will be kindly expected to perform small presentations about their systems or future plans. Based on this presentation, attendants and TEPCO experts would have a chance to discuss over the subjects and experts would make some suggestions.
