Connecting 1.7MW Hydroelectric Output to 6kV Cable Without Overheating—How To?

Hey guys. I have a situation here. Im a beginner at Electrical engineering. so here is my question: My hydroelectric power plant generates a power of 1.7megaWatts and it's cable (through transistor and resistors) must be attached to another cable that has 6kiloVolt (not kVA) electricity. the electricity company told me that the cable with 6kV electricity will overheat and burn if i attach those two cables together so i must reduce my hpp's generation to 0.5megaWatts if i want to attach the cable. is there any way to "transform" 1.7 megawatts of power into 0.5 megawatts and then into 6kilovolts so that i can attach it to 6kV electricity cable. (unfortunately i don't have the info about amperage of the 6kV cable) therefore i don't know what to do and how to fix the issue, so that i can attach the electricity generated from my HPP to the line that has 6kV running through it.?

1.7mW is 1700kVA (kilo volt ampere)

Nika, I work for an electricity company but not on the power side, but you're going way off track here.Firstly let's get your units right.  Kilo and Mega are abbreviated to k and M (note capitals for Mega) so when you say at the end "1.7mW is 1700kVA (kilo volt ampere)" that should be 1.7MW. (mW is milliWatt 1/1000 Watt which makes your statement very wrong.)  k is kilo (1000) and K is degrees Kelvin.  m is milli (1/1000) and M is Mega (1 000 000).In power transmission when you want to increase or reduce voltage you use transformers.  There are no transistors and probably no resistors made which would do what you want.You say "Is there away to "transform" 1.7 megawatts of power into 0.5 megawatts and then into 6kilovolts".   You don't transform watts into volts. What you can do is, for transmission over cables, transform (say) 240 Volts up to 6 kiloVolts.  1 MW at 240 V is 4166 Amps, but at 6 kV it is only 166 A. So at 6 kV your cables can be a lot smaller without losing power due to cable resistance.  You don't say what voltage your generator puts out - I imagine it would be higher than 250 V though.Your generator should be able to cope with a wide range of load.  It may not be able to cope with no load, and you will certainly need protection against overloads, but if your load at the other end of the cable draws 100 kW or 1,7 MW, the only change you should notice is a small change in voltage and a slight power loss - less than 10% in a well designed system.My advice to you is to brush up your knowledge on units and the relationship between Voltage, Current, Resistance and Power, and also to study transformers.  You need to know the current capacity of your 6 kV cable - it needs to be able to take 1 700 000 W / 6000 V = 283 A, and you need to estimate power loss - if it is long, you may need to get a bigger cable (still rated at 6 kV) to minimise losses.

Thank you dear David. I appreciate your assistance. I'll understand everything as soon as i learn more

Hi Nika-If your plan is to sell power to the Electricity Company, then you've got many other things to consider. If you feed power into an existing grid, the frequency and phase of your power output must be precisely controlled to match the grid, and this is no simple task. you'll also need to have a constant communication channel so your generating equipment will know when the Electricity company needs power (and how much), and when they don't.  You'll also need metering so you can tell how much power you're selling them. Is your hydro power plant already in operation?  Where is the power going now?Is the 6KV cable buried or is it on poles?  Single phase or three phase?  If you can post a picture of the cable I might be able to give you a guess as to how much current it can carry.-Rick
