Distributed Power Supply Layout to Minimize Network Voltage Drop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power distribution systems experience significant voltage drops as loads are farther away from the power supply due to increased resistance in the wiring, leading to inefficient power delivery.
Innovation Solution
A power distribution system with a network of power supplies arranged with gaps between them, allowing power to be supplied from multiple dispersed locations, reducing the distance between loads and supplies, and incorporating a controller to selectively manage power distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If power supplies are arranged close together to cover the distribution network, then the area coverage is improved, but the voltage drop increases due to longer wiring distance from the power supply to loads
Solution Approach 1:
The distribution network is divided into multiple segments, each served by a separate power supply unit. These modular units can be independently positioned to optimize both coverage area and proximity to loads, reducing the wiring distance for each segment while maintaining comprehensive area coverage.
Solution Approach 2:
Power supplies are arranged in a three-dimensional spatial configuration rather than a simple linear or planar arrangement. By utilizing vertical spacing and multi-level positioning, the system achieves both wide area coverage and short distance to loads through spatial optimization.
2Device complexity
If power supplies are positioned far from loads to reduce wiring complexity, then the installation complexity is reduced, but the voltage drop increases due to increased resistance
Solution Approach 1:
The network is segmented into multiple zones with dedicated power supplies, allowing each zone to have simplified local wiring while maintaining short distances to loads. This segmentation reduces overall wiring complexity without compromising voltage delivery.
Solution Approach 2:
Different regions of the distribution network are served by locally positioned power supplies tailored to their specific load requirements. This local optimization ensures that each area has appropriate wiring length and complexity while minimizing voltage drops through proximity to loads.
3Loss of energy
If multiple power supplies are distributed throughout the network to reduce voltage drop, then the voltage delivery is improved, but the system complexity increases
Solution Approach 1:
The distribution network is divided into independent segments, each with its own power supply unit. This modular segmentation reduces system complexity by allowing independent control and management of each segment, while still achieving reduced voltage drops through multiple distributed power sources.
Solution Approach 2:
Each distributed power supply unit operates semi-autonomously, managing its own segment of the network. This self-service capability reduces the need for complex centralized control systems while maintaining effective voltage delivery across the entire distribution network.
