Solution Overview
Problem
Existing genset synchronization methods are sub-optimal due to reliance on electrical and mechanical monitoring, resulting in slower synchronization times.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If electrical and mechanical monitoring methods are used for genset synchronization, then synchronization can be achieved, but the synchronization time is slower than desired
Solution Approach 1:
The patent replaces electrical monitoring methods with direct mechanical sensing of engine parameters. Sensors directly measure engine speed and crankshaft position mechanically, eliminating the need for complex electrical power analysis and rotor position detection systems. This mechanical substitution enables faster acquisition of synchronization data.
Solution Approach 2:
The patent introduces sensors as intermediary devices that directly interface with engine components to capture mechanical parameters. These sensors act as mediators between the engine's mechanical state and the control system, providing real-time data without the delays inherent in electrical monitoring methods.
2Ease of operation
If rotor shaft position monitoring is used for synchronization, then phase matching can be achieved, but the system complexity increases
Solution Approach 1:
The patent extracts the essential synchronization information directly from mechanical parameters (engine speed and crankshaft position) rather than deriving it from complex electrical measurements. By taking out only the necessary mechanical data points, the system simplifies the monitoring approach while maintaining synchronization accuracy.
Solution Approach 2:
The engine's mechanical components (crankshaft, flywheel) serve their dual function of power generation and synchronization reference. The crankshaft's rotational position inherently provides the phase information needed for synchronization, eliminating the need for separate position sensing systems.
Data Source
AI summary
A control system for use with a genset is disclosed. The control system may have a bus configured to receive power from the generator set, and a first sensor configured to generate a first signal indicative of a characteristic of power on the bus. The control system may also have a second sensor configured to generate a second signal indicative of an engine parameter of the generator set, and a controller in communication with the first and second sensors. The controller may be configured to synchronize an electrical output of the generator set with the power on the bus based on the first and second signals.
