Digital & Software Systems
Mayor projects in this area include:
- Design, installation, and maintenance of the Data Acquisition and Archival system for a large electric utility’s Electric System Operation Center (ESOC). The system consists of a network of four OSISoft PI servers which collect information from the Energy Management System (EMS) and makes the information available over a secured network to authorized end users. The system is designed to meet applicable NERC/FERC regulations. This project is ongoing as of the end of 2008.
- Virtual Energy Management System. Virtual–EMS® is a management information system designed to provide a secure, user-friendly means of disseminating system operating and performance information to authorized users. The original version utilized a thick-client user interface (OSISoft’s ActiveView) to provide users access to system displays maintained on a remote web server and updated in quasi real time from an OSISoft PI Server, as well as other data sources. Recently, NSEC developed a thin-client version called VEMS Portal®. Developed using Microsoft’s SharePoint Portal technology and OSISoft’s PI Server and RtPM applications, VEMS Portal® provides access to real-time and historical information from a variety of sources via a secure, thin-client, web-browser user interface. Furthermore, under VEMS Portal®, information displays can be displayed on Smart Phones (such as an Apple iPhone or Blackberry Device) providing management personnel continuous access to important system information.
System features include:
- Allows field personnel access to real-time EMS data via a secure, wireless, Internet connection to the Virtual – EMS® Server, without a direct connection to the EMS system
- Ability to go back in time and replay historical data in real-time, slow motion, or fast forward
- Allows users to access On-Demand or Scheduled reports, such as regulatory compliance or system availability reports, maintained on the Virtual – EMS® server
System functions include:
- Facilitate the daily input of work hour information using computerized database forms
- Provide instant calculations regarding regulatory work hour limits, such as the number of hours worked in the last 48 hours
- Provide instant calculations regarding actual work hours, such as weekly overtime hours worked or vacation hours available to be taken
- Facilitate the management of this information so as to allow supervisory personnel to quickly review individual work history, including compliance with regulatory requirements, overtime work history, or unscheduled absences
