Woodwards EasyGen vs. EGCP-2

10/14/2009 1:54 PM

What does the easy gen do that the EGCP doesnt already (besides the software)

Sometimes, a simple search will produce a rapid, correct answer devoid of all the cat, gremlin, vermin, dog, squirrel, alien and other opinions that usually come with the answers you get here.

Woodward Genset Controls

Granted

But all the searching does not indicate any substantial differences between the 2 units function (other than the new easy gen has the PLC software)

they still load share the same, they still sense the same

lynlynch is right. I didn't know the difference, and have only heard of the software never used it, so I did one search using Google, and this link came up right under the one lynlynch posted:

Difference between EGCP2 and easyGen 3200 LIVE PLC Questions And Answers.
www.plctalk.net/qanda/showthread.php?t=39460

There were more I just read, and found a number of differences.

Ok nevermind. Ive already looked at the links both have you listed. they do NOT inform you of any of the differences I asked about.

bravo

Primarily, the sampling rate of the easYgen is approximately 5 times greater than the EGCP-2. The increased sampling rate provides much better accuracy in the primary measurements in the presence of harmonics. Harmonics are present anywhere you have a VFD.

Initial system tuning, and subsequent tuning following any change in the system is easier with the Toolkit configuration software of the easYgen. Diagnostic and tuning trending is also much, much easier with the Toolkit software. The easYgens do not require CT calibration like the EGCP-2, thus eliminating a common tuning error.

The easYgen constantly trims voltage and frequency to rated values which improves electrical efficiency. Both the easYgen and the EGCP-2 share KW and KVAR but only the easYgen trims. The trimming improves the system efficiency when the governors or regulators are not precisely matched from generator to generator.

Your ability to do work is dependent on the horsepower being produced by the engines and the efficiency of that mechanical power being converted to electrical power. If the engines cannot produce the energy, the you do not have it to do the work. Engine operation is the most important element. When the work requires more than one engine, then it is the job of the easYgen or EGCP-2 to equally (or proportionally)share the load between the engines. The better the controller shares and the faster the controller responds to maintain proper sharing with changing loads, the grater and faster work can be performed.

If the engines are responding properly and producing maximum horsepower, and more than one engine is required, then operation of the load sharing controllers become the critical element. Remember to that speed control (governor) and the voltage regulator are the primary generating controls that are trimmed by the load sharing controller. The load sharing controller cannot correct improperly operating primary controls.

With properly running engines and with properly functioning and fast acting governors and actuators and voltage regulators, then in principle, both the easYgen or the EGCP-2 could be properly tuned to provide satisfactory system operation- without the presence of significant harmonics. However, tuning is really only accurate at that moment in time. The system is constantly changing. Engines wear, changing flow thru filters, altitude and temperature variations, fuel quality, etc. When re-tuning is required, the the easYgen has the edge over the EGCP-2.
