NTMC 2008
NTMC 2008 is a modern, Microsoft Windows XP / 2000 based master
controller used by small electric utility companies. It provides many of the
services of large SCADA systems, such as one line diagrams
(simple example on the right), remote access via telephone, LAN, WAN, or the
Internet, at small system prices.
It communicates with a variety of devices such as RTUs, PLCs, residential
meters, relays, and switches, using a host of standard, and proprietary
communications protocols. Additional, publicly available protocols are added
as needed.
NTMC is a distributed system, it can run on one computer, or
several machines when managing larger systems. Additionally, it can
communicate with other SCADA systems via its COM / DCOM, and Web Service
interfaces.
High Level Applications
 NTMC
core components perform SCADA functions such as automatic RTU polling
(see figure on the left), operation of remote switches, timed switch
management, etc. Additional components are available. Load Management
module provides a host of peak shaving, and load rotation algorithms, while Capacitor
Control component manages feeder VAr or power factor by connecting
/disconnecting capacitor banks to / from the power grid. Meter Reading module
automates remote meter reading functions, as well as billing data preparation
and forwarding to local billing departments. Remote Client provides
remote access to NTMC via LANs and telephone, while WebLink
enables users to access NTMC via the internet, and enables NTMC
to notify the users of important events via e-mail.
