Customer Story

Connecticut Light and Power Company

Connecticut Light and Power installed advanced computing and communications capabilities, 24 new Christie rear-screen DLP® projectors, allowing operators to monitor real-time data across the system to ensure minimal service interruptions.

Twenty-four Christie GraphXMASTER™ RPMS Series rear projection modules arranged in three, 2x4 straight-array formats provide vivid images to all of the control room's video walls.

The Control Room Solution

Connecticut Light and Power Company(CL&P) supplies electricity to more than 1.1 million customers in 149 cities and towns. Resident, municipal, commercial and industrial customers depend on CL&P to deliver safe and reliable power every day.

As part of its customer service commitment, CL&P recently consolidated its operation to a single Systems Operations Center (SOC) in Berlin , CT. At the end of 2003, the company brought together Regional Operation Centers from Tolland, Hartford and Waterbury , CT into one integrated facility in Berlin .

The SOC is part of the company's efforts to manage its assets and enhance the reliability of the system. By installing advanced computing and communications capabilities, the new SOC allows operators to monitor real-time data across the system to ensure minimal service interruptions.

HB Communications, Inc. was chosen to lead the installation because of their extensive background dealing with control room environments. HB has been the Northeast's leading provider of audiovisual communication solutions for nearly 60 years. With offices in Connecticut and Massachusetts , HB has the capacity to deliver its expertise to the New England area and beyond.

HB Communications managed the design and installation for the new SOC. The overall project included the construction of a main control room, simulator room for training purposes, and an overview room for meetings.

“CL&P has been a long-term client of HB Communications. The Berlin center was our seventh control room installation,” says Dana Barron, CEO, HB Communications. “With each control room that we roll out, our goal of deploying innovative solutions with best-of-breed products remains consistent.”

CL&P spent more than two years considering SOC options including fixed cubes, DLP™, LCD and plasma displays. A special SOC committee examined the different facilities HB had built around the country and chose the systems integrator based on a number of criteria.

A major obstacle for this project was the facility's eight foot ceiling. To overcome the lack of height, HB built up a soffit to 9½ feet where the console operators were located. This placed the operators at a comfortable six to eight feet from the video screen display.

The previous control center had no video technology, forcing the operators to rely on static mimic boards. With the new upgrades, the SOC combines information from the three regional centers onto three separate Command and Videowalls, each including eight projection systems. Twenty-four Christie RPMS Series rear projection modules arranged in three, 2x4 straight-array formats provide vivid images to all of the control room's videowalls.

Large Screen Displays of Santa Ana, CA customized the screens and enclosures that hold the projection modules. Large Screen Displays is a recognized leader in the rear screen technology and custom fabrication market by providing their Projected Images Pi product line and personalized Engineering Services since 1998. LDS's revolutionary control room design screen framing system allows the 53-inch cubes to be constructed without visible horizontal seams.

“Typically there would be a physical seam separation both vertically and horizontally,” says Randy Pagnan, Chief Operating Officer, Large Screen Displays. “However, our PiC EZ ThinLine Culumn seamless system eliminates the horizontal seam between images.

“Since each 2x4 videowall has only three physical seams – all on the vertical axis – the videowall provide images with minimal interruption of the graphics."

Each 2x4 videowall is comprised of tri-element screens – eight Fresnel/Clear Acrylic screens with four PiRO-BB Projected Images Black Bead Screen overlays. Two vertically adjacent Fresnel/Acrylic screens are overlaid by one PiRO-BB screen. These screens are encased in the PiC EZ ThinLine Frame with the PiC EZ ThinLine Culumn Frame inserted at the horizontal center.

Each Christie projector in the room offers 1280x1024 pixels resolution. With eight projectors per wall, operators can have up to 10,485,750 pixels on each videowall.

The set-up allows operators the flexibility of calling up and viewing an array of information displays from one-line circuit diagrams, geographical maps or multiple video sources. The dynamic video projection system means the types of information that can be displayed are endless.

"Christie RPMS Series is specifically designed for the high performance and reliability needs in a control room environment,” says Jim Gavloski, Director of Product Management, Control Room/Videowall Solutions, Christie. “Our engineers ensure our component design and selection mean low failures and minimal downtime for our customers. The RPMS design includes a modular electronics platform which boasts more than 30,000 hours MTBF (mean time between failures) – a major benefit for the 24/7 control room.”

The RPMS is ideally suited for rear projection tiled wall displays for any control room and 24/7 monitoring application.

The Christie RPMS offers true SXGA 1280x1024 resolution and ultra short throw tiling lens with 50” to 120” diagonal image size.

The CL&P installation also features a separate simulator room. The set-up offers extensive Distribution System training capabilities on scaled-down equipment that duplicates the configuration and functionality available in the main control room. The simulator room has two Christie DS30 ceiling mounted projectors and a single wall-mounted screen.

The Christie DS30 is designed to be semi-portable and is ideally suited for medium-sized fixed installation environments. With true SXGA 1280x1024 resolution, the single-chip DLP™ projector produces 3,000 ANSI lumens and can be used in high ambient light conditions.
