Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern power systems face challenges in controlling sulfur dioxide (SO2) emissions from coal-fired power plants, as traditional methods fail to effectively manage SO2 discharge across different generating sets, leading to environmental pollution and inefficiencies in energy consumption.
Innovation Solution
A concentrating control method for generating sets that inputs electric price, energy-consuming, and SO2 discharge parameters into a grid control center, using a communication network to classify and prioritize sets based on energy consumption and SO2 emission data, allowing for the selection and regulation of generating sets to minimize SO2 discharge and optimize energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional control methods prioritize lowest cost electricity purchase, then economic efficiency is improved, but SO2 discharge increases
Solution Approach 1:
The patent changes the control parameters from purely economic (electric price) to multi-dimensional parameters including energy-consuming parameters and SO2 discharge parameters. The grid control center receives and processes these additional parameters to make comprehensive control decisions that balance economic efficiency with environmental protection.
Solution Approach 2:
The patent adds new dimensions to the control system by incorporating energy-consuming parameters and SO2 discharge parameters alongside traditional electric price parameters. This multi-dimensional approach allows the system to optimize across multiple objectives simultaneously rather than single-objective optimization.
2Ease of operation
If generating sets operate without centralized control, then operational independence is maintained, but energy consumption increases
Solution Approach 1:
The patent merges the control functions of multiple generating sets into a centralized grid control center. The control center receives data from all generating sets and coordinates their operation to achieve optimal energy efficiency while maintaining the physical independence of each generating set.
Solution Approach 2:
The patent implements a feedback mechanism where the grid control center receives real-time data from generating sets including energy consumption parameters, processes this information, and sends back control signals to optimize operation. This closed-loop control enables continuous improvement of energy efficiency.
3Adaptability or versatility
If generating sets operate without centralized control, then operational flexibility is maintained, but SO2 discharge control deteriorates
Solution Approach 1:
The patent merges control coordination while maintaining operational flexibility at the generating set level. The grid control center provides high-level coordination and optimization based on SO2 discharge parameters, while individual generating sets retain the flexibility to respond to local conditions and control signals.
Solution Approach 2:
The patent adds environmental control dimensions (SO2 discharge parameters) to the existing operational framework. This allows the system to optimize for both operational flexibility and environmental performance simultaneously through multi-parameter control.
