Solution Overview
Problem
Existing systems face challenges in efficiently determining the current and total performance of locally distributed technical units generating, storing, or consuming electrical energy, particularly in decentralized energy networks, where continuous measurement and data transmission are costly and resource-intensive.
Innovation Solution
A system and method where technical units send trigger signals to a control center upon state changes, allowing the calculation of current total power using pre-determined performance values stored in the control center, reducing the need for continuous measurement and data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If continuous measurement and data transmission are implemented for each technical unit, then measurement precision and real-time performance monitoring are improved, but data volume and transmission effort increase significantly
Solution Approach 1:
The patent extracts only the essential information needed for performance determination - specifically trigger signals indicating state changes and pre-stored performance values - rather than transmitting continuous measurement data. This selective extraction reduces data volume while maintaining the ability to accurately determine current and total performance of technical units.
Solution Approach 2:
The system performs preliminary actions by pre-determining and storing performance values for each technical unit in advance. When a state change occurs, the control center retrieves these pre-stored values and combines them with trigger signals to calculate current performance, eliminating the need for continuous real-time measurement and transmission.
2Productivity
If continuous measurement and data transmission are implemented for each technical unit, then real-time performance monitoring is improved, but transmission effort and resource consumption increase
Solution Approach 1:
Instead of continuous transmission, the system uses periodic action triggered by state changes. Technical units send trigger signals only when their operational state changes, and the control center processes these discrete events to update performance calculations. This event-driven periodic transmission significantly reduces transmission effort while maintaining real-time monitoring capability.
3Quantity of substance
If pre-determined performance values are stored and trigger signals are used instead of continuous measurement, then data volume and transmission effort are reduced, but system complexity increases
Solution Approach 1:
The control center acts as an intermediary that receives trigger signals from technical units, retrieves pre-stored performance values from its database, performs the calculation of current and total performance, and determines operational commands. This centralised intermediary approach simplifies the overall system architecture by consolidating the complex processing logic in one location rather than distributing it across multiple technical units.
