Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current photovoltaic power generation systems face challenges in real-time monitoring and control due to the remote location of inverters, leading to time delays in data collection and inefficient management, especially with small-capacity inverters and the need for cost-effective monitoring methods.
Innovation Solution
A gateway apparatus that enables short-range wireless communication between photovoltaic module connection boards, inverters, environment sensors, and energy storage systems, and wired/wireless communication with remote servers, facilitating real-time data transmission and control using various communication modules such as WIFI, Bluetooth, Zigbee, LoRa, and NB-IoT.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RTU connected to inverter and sensors over wires is used for monitoring, then information can be collected, but time delay occurs in collecting information for real-time controlling
Solution Approach 1:
The patent replaces the wired mechanical connection system with a wireless communication system. The gateway apparatus uses wireless communication modules to receive information from inverters and sensors without physical wire connections, thereby eliminating the time delays associated with wired signal transmission while maintaining reliable information collection capability.
2Productivity
If inverters are located at distant places, then photovoltaic power generation can be managed, but it is difficult to instantaneously check operation status or troubles at a spot
Solution Approach 1:
The gateway apparatus serves as an intermediary device that collects information from distant inverters and sensors via wireless communication and makes it accessible through a network connection. This intermediary function allows operators to remotely monitor operation status and detect troubles instantly without needing physical access to the distant inverter locations.
3Ease of operation
If small-capacity inverters are used for large-scaled power generation, then convenient management is achieved, but monitoring is hardly performed
Solution Approach 1:
The gateway apparatus is designed with universal functionality to handle multiple types of devices including both small-capacity inverters and sensors. It can simultaneously manage power generation data from inverters and environmental data from sensors, providing comprehensive monitoring capability that works effectively with small-capacity inverter systems while maintaining ease of management.
