Managing Wind Power Generation and Transmission Equipment APPLICATION NOTE Executive Overview Wind powered electricity generation is one of the fastest growing sectors of the American economy. This rapid growth has presented a challenge to those organizations charged with operating and managing farflung equipment. Not only is it imperative to satisfy customer demand for faster service and improved asset availability, it is increasingly important to do so while reducing service related costs and enhancing profitability. MultiLink, Inc. has provided cost containment and remote site service solutions for hundreds of utilities and equipment service providers for over 25 years. The Problem Wind turbines are being installed as fast as they can be manufactured. With this unprecedented growth comes the need to remote access the control interfaces of the equipment – power monitors and conditioners, relays, meters, and telemetry data. Engineers must be able to access the management interfaces of these devices from remote operations centers or while on the road in order to assure maximum service availability. Cost of Network Infrastructure: With the number of management interfaces growing, telecommunication costs to access them are also growing. In many cases a separate phone line is installed for each device, with an attached monthly cost of about $50 (based on national average). At sites with four phone lines, costs can add up to $2,400 per year per site. Limited Resources: With the fast installation pace of new projects, availability of support staff is at a premium. Managing remote site equipment frequently puts maintenance personnel out of contact for hours, or even days at a time, frequently at expensive overtime labor rates. In addition, cost per service dispatch has risen 33% from 2006 through 2009.

Managing Wind Power Generation and Transmission Equipment  

APPLICATION NOTE

Executive Overview

Wind powered electricity generation is one of the fastest growing  sectors of the American economy.  This rapid growth has presented a challenge to those organizations charged with operating and managing far‐flung equipment. Not only is it imperative to satisfy customer  demand for faster service and improved asset availability, it is  increasingly important to do so while reducing service related costs and enhancing profitability. Multi‐Link, Inc. has provided cost containment  and remote site service solutions for hundreds of utilities and equipment service providers for over 25 years.

The Problem

Wind turbines are being installed as fast as they can be manufactured.  With this unprecedented growth comes the need to remote access the control interfaces of the equipment – power monitors and conditioners, relays, meters, and telemetry data.  Engineers must be able to access the management interfaces of these devices from remote operations centers or while on the road in order to assure maximum service availability.    

Cost of Network Infrastructure: 

With the number of management interfaces growing, telecommunication costs to access them are also growing.  In many cases a separate phone line is installed for each device, with an attached monthly cost of about $50 (based on national average).  At sites with four phone lines, costs can add up to $2,400 per year per site.  

Limited Resources:   

With the fast installation pace of new projects, availability of support staff is at a premium.  Managing remote site equipment frequently puts maintenance personnel out of contact for hours, or even days at a time, frequently at expensive overtime labor rates.  In addition, cost per   service dispatch has risen 33% from 2006 through 2009.  

APPLICATIONS

o Substation Communications

o Modem Polling

o Automated Meter Reading

o Service Port Access

o Remote Equipment Maintenance

The Solution

Multi‐Link offers a suite of American made products that allow you to eliminate telephone lines as well as remotely reboot equipment.  The savings in time and more efficient utilization of limited resources optimize support operations.  Example 1  

  Maintenance and operations organizations are responsible for wind farms constructed across a vast, ever‐growing territory.  This is putting a strain on staff trying to keep up with equipment issues many miles apart.  In many cases, telemetry equipment needs to be powered up on a regular basis, after which it is again turned off.  For staff trying to keep up with field problems as well as regular operations, it is becoming a daily challenge to meet service level demands.  For management this translates into extra costs for overtime pay, service call dispatches, fuel, etc.  The Power Stone® helps contain those costs.  The Power Stone is a phone call activated AC power controller used to reboot and power up/down remote equipment.  Connect The Power Stone to equipment and a phone line to gain complete power control anywhere you can place a phone call.  Because The Power Stone is activated with a telephone call, power to the attached equipment can be controlled from the operations center or even via cell phone by staff who are traveling.  The Power Stone makes a perfect complement to the Polnet ACP, providing complete control of remote equipment.    Example 2 Remote connectivity to control ports provides access to critical operational information.  In applications normally using in‐network connectivity, secured access using out‐of‐band techniques via the Public Switched Telephone Network (PSTN) assures that no site can become completely isolated in the event of network failure.

  Installing a Polnet® ACP (ACP), a secure line sharing device, wherever multiple phone lines are required for out‐of‐band access can reduce expenses by thousands of dollars.  Many times each location is able to reduce the requirement for four or more phone lines, saving $200‐$350 per month, or more. Electric utilities are saving thousands of dollars utilizing this equipment today, with over 10,000 ACPs now installed.  One such company has over 1,000 ACPs, saving over $1,000,000 per year in reduced telecom charges.

 Summary In today’s economic environment, successful power generation operations will require innovative solutions to keep pace with demand while maintaining high levels of service.  Reducing telecommunication costs and making efficient use of resources are key elements stretching budget dollars.  Multi‐Link products have been used by electric companies to accomplish these goals for over 15 years.
