Diesel electric boat, efficiency? - diesel generator efficiency
I have a diesel two Etek (48v ISH / connected 8hp) motors, generators and two Etek motors and engines with two propellers on a catamaran.
The problem:
There is a variable load at a certain speed. This means that when the boat rises with the increase of the load to a theoretical maximum, and again when the ship sinks the other side of the shaft, + 50-foot waves can be important if this is important.
What is the most effective way to fight against this plant, taking into account a variable load.
I have studied several systems:
With a variable speed constant Actuator Controller governor. That means the quantity controls) to fuel the engine to keep a certain speed (usually for the production of alternating current. And shooters, two, three front channels and rear and rear.
With a controller for each engine shooter. I assume that the output voltage is proportional to input voltage regulator controlled by the governor.
Or just two switches and differ only in the standard voltage control motor speed.
Another question, ifTime is the way to remove excess energy, for example, in the excess energy generated by the engine to take it was the manufacturer of water or a water heater. I saw some 48v solar charge controller, which have a transfer function.
Efficiency is a priority because the amount of fuel can be made is limited, and this applies to long term.

Diesel Generator Efficiency Diesel Electric Boat, Efficiency?

A little old technology that is used to turbo-electric drive in the 2nd World War was the use of a "system rototrol (Ward Leonard) to control. It was a tightly coupled motor-generator (MG) started for the excitation control system for DC-powered generators are used. This supply voltage is determined by applying a voltage and motor current, so that the gun was again generated excitement restated restated the MG series of output, then the main output of the generator. Finally, the proposed mechanism of control of the generator output load of the main DC motor and power. It was a simple and robust Electro Mechanical speed governor, which worked well enough to minimize fluxuations speed and performance in rough seas.
Today you can see the same thing with the electronic speed control. Same concepts, monitoring the voltage and current to the motor and generator excitation, then adjust accordingly. Control of emotion is the best way to control the generator power and speed in response to the rough seas. The Governoracts as the main sponsor of the payload of the horse and responds to changes in the load, but in a slower manner.
Distillation of the fresh water, with the waste heat from the water jacket of the engine and the use of ships that can operate the electrical energy for pumps and controls to be done. Large ships can use a generator shaft to provide a little power. This happens when the ship is cruising at a constant speed, it is least expected. This is done to increase efficiency may be less efficient generator of ships held in May, while the gene-axis is in operation and the load on the engine more efficient propulsion extrat principal.
We also consider the delay time of entry threw circuit, solenoid valve, engine response, making the pair.
To avoid feedback controller response.
Can damage equipment.
Consider the time Sinsoidial Avg posts [Comments diffuse controller].
