Solution Overview
Problem
Existing power distribution systems face inefficiencies and frequent tap changes in large industrial settings, leading to increased failure rates and inefficiencies due to sudden voltage drops when preset threshold levels are set to prevent device shutdowns.
Innovation Solution
A method and system that continuously detect and compute deviant voltage levels based on varying electrical consumption, using a processor and voltage regulator to adjust voltage levels in real-time, ensuring they remain within predetermined limits, thereby reducing unnecessary tap changes and maintaining efficient power distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If preset threshold levels are set high to prevent device shutdown, then device reliability is improved, but system efficiency deteriorates due to unnecessary voltage maintenance
Solution Approach 1:
The patent implements dynamic threshold adjustment by continuously monitoring load conditions and adapting the voltage threshold levels in real-time. When load is high, thresholds are set to prevent shutdown; when load is low, thresholds are relaxed to allow efficient voltage reduction, eliminating the need for fixed high thresholds that waste energy during light loading.
Solution Approach 2:
The system changes the voltage threshold parameters dynamically based on measured load conditions. The controller adjusts the threshold levels according to the actual electrical consumption patterns, transitioning between different operational states (normal operation, approach to shutdown, shutdown prevention) to optimize both reliability and efficiency under varying conditions.
2Stability of the object's composition
If tap change frequency is increased to maintain voltage levels, then voltage stability is improved, but tap mechanism reliability deteriorates due to increased failure rate
Solution Approach 1:
The system performs preliminary detection of voltage trends and load changes before actual voltage instability occurs. By monitoring approach-to-threshold conditions and predicting future voltage levels based on current consumption patterns, the controller can take preventive action only when necessary, avoiding frequent reactive tap changes that wear the mechanism.
Solution Approach 2:
The patent implements a feedback control system that continuously monitors voltage levels, load conditions, and threshold approach states. This feedback enables intelligent decision-making about when tap changes are actually needed versus when voltage can be allowed to vary within acceptable ranges, reducing unnecessary tap operations while maintaining stability when required.
