Solution Overview
Problem
Existing power distribution systems face challenges in efficiently managing power transitions between primary and secondary sources, particularly in hybrid low voltage systems where devices operate on different power types and amounts, leading to inefficiencies and safety concerns during peak and off-peak hours.
Innovation Solution
A hybrid distributed low voltage power system is introduced, comprising a primary power source that distributes line voltage power during one mode and a secondary power source that generates a reserve signal during another mode, with a power distribution module (PDM) that converts line voltage power to low-voltage signals and reserve signals for LV devices, ensuring seamless operation and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a primary power source distributes line voltage power during normal operation, then power delivery capability is improved, but system reliability deteriorates when the primary power source fails
Solution Approach 1:
The secondary power source is pre-configured and charged during normal operation (first mode) when the primary power source is functioning. This preliminary action ensures that when the primary power source fails, the secondary power source is already ready to immediately take over without interruption to the LV devices.
Solution Approach 2:
The power distribution module (PDM) acts as an intermediary between the primary/secondary power sources and the LV devices. It automatically detects power source availability and seamlessly switches between them, mediating the transition to maintain continuous power delivery to devices regardless of primary source status.
2Adaptability or versatility
If power distribution systems use different power types and amounts for various devices, then device adaptability is improved, but system complexity increases
Solution Approach 1:
The power distribution module (PDM) is designed with multi-functionality to handle different power types (line voltage and low voltage) and power amounts. It can operate in multiple modes: distributing line voltage during normal operation, switching to low voltage during power failures, and managing transitions between these states, thereby providing universal power distribution capability.
Solution Approach 2:
The power distribution system is segmented into distinct functional components: the primary power source for line voltage distribution, the secondary power source for low voltage distribution, and the PDM for coordination. This segmentation allows each component to specialize in specific power types while the overall system maintains adaptability through their coordinated interaction.
3Reliability
If seamless power transition between primary and secondary sources is implemented, then system reliability is improved, but transition control complexity increases
Solution Approach 1:
The power distribution module (PDM) incorporates self-service capabilities by automatically detecting the status of the primary power source and autonomously initiating the transition to the secondary power source without external intervention. The system monitors itself and performs the switching operation based on pre-programmed logic, ensuring seamless transition while minimizing control complexity.
