The Special Technical Specifications (STS) of each Substation provide additional requirements and detailed information concerning the scope.

43. Purpose and Objectives of acs tp ss

    1. Purpose of acs tp of the Substation

The automated process control system of substation has been designed for:

• automation of substation process control and diagnostics functions with necessary information allocation at all the levels of operating hierarchy in normal, emergency and post emergency substation operation modes;

• improvement of substation operation reliability;

• prevention of personnel’s errors;

• reduction of operating costs.

2. Objectives of the acs tp of the Substation

The objectives of the ACS TP are as follows:

• Increasing the reliability of the SS control system and on this basis to increase the reliability of electricity supply to consumers.

• Creation of reliable providing of personnel with information about substation technological process in normal, repair, emergency and post emergency modes.

• Creation of united complex of technical and software aids for monitoring, diagnostics and control of substation equipment with integration of RP & SA and measurement system.

• Expanding the functionality of SS control system by taking advantage of microprocessor technology.

• Reduce the accident rate of SS main equipment.

• SS operating personnel errors minimization.

• Reduce the costs of repair and restoration works and routine maintenance of SS main equipment.

• Adequate analysis of SS equipment failures.

• Lower operating costs, reduction of quantity of SS operating personnel.

• Automation of SS equipment mode control process.

• Less time of switching operation.

• Higher quality and efficiency of centralized dispatcher control of SS.

• Creation of conditions for safe operation of SS main equipment and improvement of operating personnel’s labor safety level.

• Longer service life and higher operation reliability of SS main equipment, RP & SA and measuring devices due to optimization of operating modes and use of up-to-date diagnostics methods.
