I've found that continuously generating 75KVA power basically problem free from a Kokler 100KW standby generator over 35,000 hours continuous production is the smallest part of an electrical generation project. More free fuel is available, but the ideas max out at a variable 5 KW to 50 KW so far. I could, would and do willing tell interested people how good quality flare gas from associated gas off the oil well casing of even a marginal well can produce more power than any ordinary farm can utilize on a continuous basis. Perhaps someone can comment on what would solve the requirements of the grid authority and in the least complicated and costly way in order to sell the excess to an electrical utility.
Despite several years of researching grid tying to a provincial power utility and searching the internet, I have yet to come up with a relatively simply grid connection for synchronous power production...outside the control units equivalent to the power companies commissioning of a new unit at their large generating sites.
The solar industry has a wide selection of grid tied solar inverters that accept high voltage (max 1000Vdc) DC bus sources. (most usual from conventional strings of photovoltaic solar panels). Those inverters are considered and accepted for near immediate connection to electrical grids such as I was and am interested in applying to access.
What pitfalls and oversights would there be in connecting 480VAC synchronous generation to an Allen Bradley Variable Frequency Drive (3ph 480V) input? Then using the) accessible DC bus running at close to 670 VDC ( and which could be parallelled with other similar VFD's in a common bus system.) In any case the VFD DC+ bus would feed the solar inverter instead of the solar panel string.
Any hints on DC amperage control etc that would be essential to feeding this into an Allen Bradley (Yaskawa) PVI23L-480 grid tied solar inverter to hopefully output about 23 KW of 3 phase 480VAC power approved into the power company infrastructure would be deeply appreciated and maybe even reciprocated.
Alternatively; any other suggestions about mechanically connecting induction motor/induction generation would be appreciated. I've tried a 20 HP test unit which works; but the required relays and certification appears to make that a non-starter.
I've come to the conclusion that the least resistance with inspection might come with the proven solar grid tied inverters; and feeding them with appropriate; but consistent and fixed BC bus required voltages from VFD(s); and hope that any required current control to protect the solar inverter is a simple matter.
There's a market for this (which I'm not particularly interested in being involved in); but the testing and commissioning aspects are right down my alley.
