SCADA / Substation Automation
ASHIDA has Designed, Developed & Perfected SCADA (Supervisory Control & Data Acquisition System) system especially for Substation Automation for Electrical Utility application – ASCADA-SAS. This is a very powerful computerized system, and brings control of entire substation at your fingertips. As per the specific requirements & the needs of the client we Design, Manufacture, Supply, Install & Commission entire ASHIDA SCADA System on turnkey basis. ASHIDA has successfully completed more than 75 projects at various voltage levels from 11KV to 400KV.
ASHIDA Substation Automation System (ASCADA-SAS) for Utilities is complete solution for remote control & Monitoring of switching / feeding station. The system consists of SCADA Software on servers at Remote Control Center (RCC Equipment), Communication Media and ARTUs at the remote stations.
The ASHIDA RTU is a single unit for the entire substation for monitoring & controlling all bays in the substation. The ARTU has a redundant power supply. The ARTU can communicate with the Numerical Relays and Energy Meters and can be interlinked with these through Fiber Optic cable / copper cable in ring /star network. The ARTU can be time-synchronized from remote. In Substation Automation apart from basic protection functions, relay continuously monitors different status flags.
The SCADA system is a very important tool to monitor power system effectively. Ashida has developed a very versatile SCADA system software which can communicate with variety of relays / RTU having different protocols such as IEC 60870-5-103. /101, DNP 3, MODBUS, etc.
The concepts we have used in our ASHIDA SCADA system employ the Remote Terminal Units (RTUs), Station Controller, Intelligent Electronic Devices (FCCM) and integrating different makes of Bay Controller Units, Numerical Protection Relays and Multi Function Meters with integration of multiple protocols. The ASHIDA SCADA system covers complete Energy Management system, Alarms & Status Monitoring Recording & Control Outputs i.e. to measure digital inputs, analog inputs & control outputs and complete protection Relay analysis. The SCADA shall support wide range of industry standard protocol such as IEC 61850, IEC 60870-5-101, IEC 60870-5-103, MODBUS & DNP. There are multiple options for backend Data base Server e.g. SQL server etc.
The ASHIDA SCADA supports communication through different media such as Ethernet, Radio VHF, Fiber Optic, GSM, GPRS, VSAT, P&T Line, PLCC Communication, ADSS Communication etc.
The ASCADA-SAS (ASHIDA SCADA Software Systems) is Windows operating system based, extremely user-friendly Software and works in a point-n-click environment. The ASCADA - SAS Software interrogates SCADA modules installed on individual bays/post. All such information collected from various modules is then processed, recorded & presented to the user in form of colored mimic diagrams, event lists, alarm lists, graphs, summary screens & annunciation windows etc. These can be further conferred as per user requirements for customized audio alarms, etc. In this mimic display screen, monitored component can be selected and operated with a simple point-n-click procedure. The user has an option to control individual bays based on this data. Multiple such sub-stations can be monitored from a single location. The recorded data is used to generate reports like history event, feeder logs, energy audits, interruption, outage or tripping reports, history graphs and other analytical reports as per user requirements. Any of these can be exported to all popular word processing & spread sheet formats.
