    1. Control Process Automation

To achieve a high level of object’s automation, the automated control system should perform switching operations according to the technological regulations. Regulations shall be agreed with the Employer at the stage of technical design.

The switching operations shall be carried out according to procedure with the system time and messages recording related to the given switching operation.

After every switching operation the corresponding changes in the object’s diagram shall be displayed at WS. In case it is not possible to carry out an operation the automated control system shall notify the personnel of the causes that make the SU operation impossible. Operating personnel may abort switching operation and switch to manual control.

The software (hardware) interlocking (to be defined by design) excluding simultaneous control from different location shall be provided for electrical equipment control (local, remote).

All personnel actions of electrical equipment control from WS or on the spot shall be recorded in the ACS TP archives with time tag, method of control and of the operator.

The archive shall also contain recorded operation on changing the switching units mode of control (“local” – “remote”).

Notes

From WS of BEN (ES) operation and dispatching personnel

All control switching devices are implemented in full – the main way to control for operating personnel on duty ( at the substation without operating personnel)

From WS of SS operating personnel

All control switching devices are implemented in full – the main way to control for operating personnel on duty

- the main control method for maintenance personnel (EOD, operational outreach) at the substation without operating personnel

From controls switching devices (from touch screen terminal control) or mimic panel of bay control cabinet

It is used only in case of failure of SHS ACS upper level. The control commands are recorded in the system, operational block is executed by means of bay control terminals.

At the place – from control cabinet switching device.

Emergency control method – in case of failure of all means of ACS TP and secondary switching devices.

For electrical equipment control (local, remote) shall be provided:

  • software and hardware interlocking, to prevent simultaneous control from different workstation,

  • process interlocking logic

All action of the operating personnel, regardless of the control level, shall be recorded in the ACS TP archives, indicating time, control method, performed operation and the identification of operator.

Changing the switching units mode of control, other devices that have a mode switch “ local”-“remote” should be recorded in the archives.

Archiving must fulfill the following main functions:

  • Data archiving and storage

  • Data protection

  • Presentation of archived data on request
