Example : The Screens below show examples of a Municipal Power Plant SCADA systems provided by NTSI,in this case Delano , Springfield and Janesville Municipal Utilities in Minnesota. The screens display live plant instrument readings for all parts of the facility electrical system.
The SCADA computers are utilizing MS Server 2008, MSSQL Server 2008 and GE Cimpilicty HMI, configured to move historical data to MSSQL Database. The system utilizes various types of OPC server client software as well as special communications protocols for PLC RTUs concentrators interface.
The customers had several custom reporting configurations that were needed, some of which are printed automatically each morning, eliminating the the need for manual readings and hand written data entry. (See examples on page 2)
The daily reports printed in the example display all critical voltages, pressures, transformer tap positions, feeder kwh, substations interconnect data, generator fuel supplies, power plant dc battery voltages, battery system alarms, city water tower levels and modbus networks status to name some key points. (See examples on page 2)
Two of the important reporting benefits are that report viewing can be either inner office web based over intranet or local excel based allowing customizing of the data viewing and desired functionality.
The system is capable of automatically paging the utility on call technician if the scada system senses a plant alarm event.

NTSI customers wanted to be able to monitor weather conditions on the SCADA system computers . NTSI selected the Davis Instruments Vantage Pro 2 and Weather View 32 Software, The Weather view 32 screen above is developed and provided by Weather view 32 Software as a default home screen.
Weather View provides great functionality and basic historical reporting. The only issue for NTSI was that we could not retrieve Weather View historical data and combine in our MSSQL master database. This was do to incompatibility and format issues within Weather View 32 software.
NTSI found that Weather View 32 is great software with excellent functionality when used with the Davis Instruments Vantage Pro 2 as a stand alone Weather monitoring solution.
