Substation Automation System Clause Samples

The Substation Automation System clause defines the requirements and standards for the automation and control systems within an electrical substation. It typically outlines the necessary hardware and software components, such as programmable logic controllers, communication networks, and human-machine interfaces, as well as their integration and interoperability. This clause ensures that the substation operates efficiently, safely, and reliably by automating monitoring, protection, and control functions, thereby reducing manual intervention and minimizing the risk of operational errors.
Substation Automation System a) For all the new substations, state of art Substation Automation System (SAS) conforming to IEC-61850 shall be provided. The distributed architecture shall be used for Substation Automation System, where the controls shall be provided through Bay Control Units. The Bay Control Unit is to be provided bay wise for voltage level 220 kV and above. All Bay Control Units as well as protection units are normally connected through an Optical fibre high speed network. The control and monitoring of circuit breaker, dis-connector, re-setting of relays etc. can be done from Human Machine Interface (HMI) from the Control Room.

Substation Automation System a) For all the new substations, state of art Substation Automation System (SAS) conforming to IEC-61850 shall be provided. The distributed architecture shall be used for Substation Automation System, where the controls shall be provided through Bay Control Units. The Bay Control Unit is to be provided bay wise for voltage level 400 kV and above. All Bay Control Units as well as protection units are normally connected through an Optical fiber high speed network. The control and monitoring of circuit breaker, dis-connector, re- setting of relays etc. can be done from Human Machine Interface (HMI) from the Control Room. The functions of control, annunciation, disturbance recording, event logging and measurement of electrical parameters shall be integrated in the Substation Automation System (SAS). At new substations, the Substation Automation System (SAS) shall be suitable for the operation and monitoring of the complete substation including proposed future bays/elements. In the existing substations with Substation Automation System (SAS), augmentation of existing SAS shall be done for bays under present scope. In the existing Substations where Substation automation is not provided, control functions shall be done through control panels. Necessary gateway and modems (as required) shall be provided to send data to RLDC/SLDC as per their requirement and shall be provisioned with 2+2 redundancy i.e. 2 channels for Main Control Centre and 2 channels for Backup Control Centre. In order to meet this requirement, suitable redundancy at port and card level need to be ensured by the TSP to avoid any single point of failure which may lead to interruption in real time grid operation. Accordingly, all the hardware for communication services of the station as stated above shall support dual redundancy for data transmission of station to respective main and backup RLDCs. Any augmentation work at RLDC/SLDC is excluded from TSP’s scope. However, all the configuration work at substation end required to send data to RLDC/SLDC shall be in the scope of TSP.

The Substation is being executed with Process bus automation based on IEC 61850 using sampled values. Merging units (MU), Switchgear control unit (SGC), Digital interface for transformer (DIT) and Digital interface for reactor (DIR) are envisaged to interface with primary equipment. Station bus and process bus are proposed with PRP based redundant network. A tentative architecture showing automation philosophy is attached for reference as Appendix-1. Centralised type bus bar protection is envisaged which subscribes to Sampled Values from the Process Bus. The proposed Process bus shall be time synchronized with PTP profiles: IEEE C37.238- 2017 and IEC/IEEE ▇▇▇▇▇-▇-▇ 2016. Following points shall be required for extension works under present scope: 1.
