Solution Overview

Problem

Existing power monitoring and control systems for multiple engine generators on separate buses lack the functionality to provide advanced operation and control features, such as automatic generator starting, load prioritization, and bus optimization, when compared to single bus systems.

Innovation Solution

A multiple bus generator and load control monitoring system that allows for increased functionality by separating or combining multiple bus structures using isolation devices, with a monitoring system controller that receives and processes information from each bus to determine operating parameters and control the system accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple bus systems are used to provide power to different loads, then system reliability and power distribution capability are improved, but automation and control functionality are lost

Engineering Contradiction:
Improvesystem reliabilityVSAvoidautomation functionality
Core Design Contradiction:
ReliabilityVSExtent of automation

Solution Approach 1:

The monitoring system controller is designed to perform multiple functions: it monitors power quality parameters (voltage, frequency, harmonics) across multiple buses, controls generator operation, manages load distribution, and provides system protection. This single controller integrates the automation capabilities needed for complex multi-bus systems, making the system both reliable and automated.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system continuously monitors power quality parameters, generator performance, and load conditions, then uses this feedback to automatically adjust generator output, control load distribution, and maintain system stability. The controller receives real-time data from multiple buses and automatically makes control decisions to maintain optimal operation.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If multiple separate bus structures are used, then power distribution flexibility is improved, but control complexity increases

Engineering Contradiction:
Improvepower distribution flexibilityVSAvoidcontrol complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The power distribution system is divided into multiple independent bus segments, each capable of operating autonomously. The monitoring system controller manages each bus separately, allowing flexible power distribution while maintaining simplified control through modular architecture. Each bus can be independently monitored and controlled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple separate bus structures are combined under a single monitoring system controller that provides unified management. The controller integrates information from all buses and coordinates control actions across the entire system, reducing overall control complexity while maintaining the flexibility benefits of separate bus structures.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If advanced control features are implemented in single bus systems, then operation efficiency is improved, but system complexity increases

Engineering Contradiction:
Improveoperation efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The monitoring system controller implements multiple advanced control features including automatic generator starting, load prioritization, bus optimization, and power quality management within a single integrated platform. This provides single-bus level automation efficiency for multi-bus systems without proportionally increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system automatically adjusts operational parameters such as generator output levels, load distribution ratios, and power flow directions based on real-time system conditions. These dynamic parameter changes enable efficient operation while the automated parameter management keeps system complexity manageable.

Inventive Principle:
Principle #35Parameter changes

AI summary

Multiple bus generator and load control monitoring system for electrical switchgear is provided. In one arrangement, the system is designed to allow for the increased functionality of a single bus system to be used in multiple bus systems wherein the multiple buses are separated or combined together to act as a single bus. Each bus within the multiple bus system may be able to utilize increased functionality of a typical generator bus and load control system independently if separated. Separate bus structures may be separated by some sort of isolation device, for example: a circuit breaker, transfer switch, or the like. If the bus segments are connected together via isolation devices, then the combination of the overall connected bus structure will act as a single entity, while containing enhanced automation functions.
