Solution Overview

Problem

Developing a SCADA system for large-scale wind power farms is challenging due to geographical constraints, non-standard factors among wind power generators, and the complexity of managing stability and reliability, making it difficult to verify functionality and stability effectively, especially when malfunctioning could lead to costly breakdowns.

Innovation Solution

An apparatus that simulates a wind power farm by creating a virtual environment using a wind power farm controller, simulation platforms, and generators, allowing for remote control and monitoring, and managing resources to test the SCADA system's functionality and stability in an integrated manner across multiple systems, using protocols like OPC, Modbus, or MMS for data exchange.

VSEngineering Contradiction Analysis

1Productivity

If a large-scale wind power farm is located in high mountainous or coastal regions to generate wind power energy, then wind power generation efficiency is improved, but the reliability of voltage control and electric power quality is lowered when linked to the system

Engineering Contradiction:

Solution Approach 1:

The patent applies preliminary action by conducting verification tests and effects evaluations in a simulated environment before the actual wind power farm is deployed. The simulation apparatus allows testing of voltage control strategies and power quality management under various operating conditions beforehand, enabling operators to identify and resolve potential issues before they affect the real system's reliability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The simulation apparatus serves as an intermediary between the wind power farm and the actual grid system. It provides a virtual testing ground that mediates the connection by allowing preliminary verification of control systems and power quality management strategies without directly impacting the real grid's stability

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a SCADA system is installed to monitor and control the wind power farm, then operational stability is improved, but the complexity of verifying system functionality and stability is increased

Engineering Contradiction:

Solution Approach 1:

The patent applies copying by creating a virtual replica of the wind power farm and its SCADA system in the simulation apparatus. This copy allows comprehensive verification of system functionality and stability without the complexity of testing on the actual system, enabling thorough validation of monitoring and control functions in a controlled environment

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The simulation apparatus extracts the verification function from the actual SCADA system. By separating the testing and validation activities into a dedicated simulation environment, the patent simplifies the verification process while maintaining the operational stability benefits of the full SCADA system

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If multiple wind power generators with non-standard factors are managed in a large-scale farm, then power generation capacity is improved, but the difficulty of managing stability and reliability is increased

Engineering Contradiction:

Solution Approach 1:

The simulation apparatus applies universality by providing a single integrated platform that can simulate and test multiple different types of wind power generators with various non-standard factors. The system handles diverse generator configurations, control strategies, and operating conditions through a unified simulation environment, simplifying the management of heterogeneous wind power farms

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