Abstract of Invention:

...Background:

...Statement of problem: briefly explain the problem solved with the invention. If applicable explain how the

competition solves the problem.

In traditional way the diesel's power shall be consumed by the hydraulic system, meanwhile in load testing, the fuel consumed by diesel shall be wasted, because the energy is difficulty to be recycled by using hydraulic dynamometer. So the traditional marine diesel load testing method is not good for fuel saving, cost saving and environment protection. An Electrical Drive System with Control Unit can be instead of hydraulic dynamometer as diesel's load testing method or tool, which can convert the mechanical power to useable electrical power when diesel is in load testing. Comparing with the hydraulic dynamometer, the Electrical Drive System for marine diesel Load Testing can recycle the power to achieve fuel saving, cost saving and environment.

...Novel features: how does the invention differ from anything done before by ABB or by competition

The Electrical Drive System is based on Variable Frequency Drive and Motor. From the configuration, which is similar with ABB or competitor's VFD solution, but the VFD solution is to offer mechanical power for consumer, the Electrical Drive System for diesel load testing absorbs the diesel's power and recycles the power consumed during diesel's load testing.

...Business benefits: how does the invention make things better - is it...
