Emergency Generator Efficiency via Energy Storage System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional emergency generators face efficiency degradation and economic inefficiencies due to the need to disconnect loads during power failures, leading to potential power failures and reduced lifespan, as they struggle to maintain power generation capacity with varying load demands.
Innovation Solution
A method utilizing an energy storage system (ESS) to handle load demands by supplying stored power when the emergency generator's output is insufficient and storing surplus power, allowing the generator to operate at maximum efficiency without disconnecting loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the emergency generator maintains power generation capacity to satisfy all load demand, then power supply reliability is improved, but driving efficiency deteriorates and economic efficiency is lowered
Solution Approach 1:
An energy storage system is introduced as an intermediary component between the emergency generator and the loads. The energy storage system absorbs excess power when generation exceeds demand and releases power when demand exceeds generation, enabling the generator to operate at optimal capacity while maintaining reliable power supply to all loads.
2Reliability
If the emergency generator operates at maximum power generation capacity, then all load demand is satisfied, but power waste increases and lifespan is reduced
Solution Approach 1:
Instead of wasting excess power generated by the emergency generator, the system recovers and stores it in the energy storage system. This recovered energy is then available for use during periods when generation is insufficient, eliminating power waste while maintaining adequate supply capacity.
3Productivity
If loads are disconnected according to generator capacity specifications, then generator efficiency is maintained, but power failure occurs in some loads
Solution Approach 1:
The energy storage system performs preliminary action by storing power in advance when generation exceeds demand. This pre-stored energy is then released to prevent power failures in loads during periods when generator output is insufficient, eliminating the need to disconnect loads while maintaining generator efficiency.
