SYSTEM COMPONENTS Operator's Station The Operator's Station is the key human machine interface within a substation. It acquires, processes, displays and records all the information received by devices on bay level and transmits operators' instructions to the devices on bay level to fulfill the monitoring, control and administration on all the equipment in the substation while multiple application functions are integrated in the station.

Single Line Drawing The single line drawing (SLD) gives the complete overview of the substation. It contains details about the Dynamic Busbar colouring feature, Status of switches and the details of the primary and secondary equipment and display of metering parameters.

Reporting There is a strong MIS reporting software integrated to the HMI software. The reporting system allows the user to retrieve different kinds of reports according to the different functional groups in the organization. The data retrieval is time-bound at the user specified frequency intervals. Several reporting options are available to meet the customer requirements: Ø Log Report

Ø Outage Reports

Ø Energy Report

Ø Tripping Reports

Ø Power Consumption Report

Ø Event Log Reports

Ø Energy Accounting

Ø Breakdown Reports

Ø Energy Loss Analysis

Ø Tamper Report

Ø Peak load of the system·

Additionally, the following features are available in the Reporting Module: Ø Exporting facility to Microsoft Excel, Microsoft Word and PDF Ø Back-up of data at user specified intervals Ø 2D and 3D graphs (Line, Area, Pie, Bar etc.)
