A little bit about the Power System Experience Center or PSEC. The PSEC is a full scale power system that recreates real power system issues and provides solutions to these issues.
The purpose of this facility is, like I just mentioned, demonstrate in a “hands-on” environment possible power quality issues and how to solve these issues. We educate and help end users in equipment selection to ensure that they are choosing the best possible product for their needs. There is a lot of confusion and misinformation in the marketplace about power systems, and we work with customers to answer any questions they may have. And finally we also do research, development, and equipment testing here as well.
The first project I worked on was the Fish Tank Demonstration. The fish tank demo shows three different methods of motor control in power systems by pumping water through tubes.
The first tube on the left is controlled by restrictive valve control. What’s happening here is that the pump runs at 100% power for the entire duration of the demo, and the speed of the flow is slowed by valves inside the tubes. Having the motor run at full power the entire time is a very inefficient way of running a motor. It can be compared to driving a car with your foot down on the gas, and using the brake to control your speed…it’s not a very efficient way of controlling power.
The second motor is hooked up to a gravity storage tank, similar to a water tower. This motor still runs at full power, but in this case it only needs to run for half of the time. It runs until it fills up the tank, and once the tank is full, the motor shuts down, and allows gravity to do the work and distribute water. There is a cost savings here because you run the motor for less time, and for a situation like this you can pump water at night when power is cheaper and let gravity push water through the day.
The third motor is controlled by a Variable Frequency Drive or VFD. The idea behind the VFD is that it runs the motor the entire time, but does so much more efficiently by lowering the frequency of the motor. In this situation, you can perform the same function at about half the power or even less. Power has a cubic relationship to frequency, so if you were able to reduce the frequency by half, that would be ½ to the third, so it would reduce the power to 1/8.
