Remote Monitoring and Management System Solution for Photovoltaic Power Stations on Abandoned Mines

 

Industry Background

China is the world's largest coal producer, and traditional mining activities have resulted in significant idle land resources and ecological damage. According to data from the National Energy Administration, by 2025, the area of closed coal mine sites nationwide will exceed 2 million hectares, with approximately 40% of them possessing potential for photovoltaic (PV) development. Transforming abandoned mines into PV power stations not only revitalizes idle land but also achieves dual benefits of environmental governance and clean energy production through the "PV + ecological restoration" model.

However, PV power stations on abandoned mines generally exhibit characteristics such as remote geographical locations, harsh environments, and dispersed distribution, posing numerous challenges to the operation and management of these stations. Traditional manual inspection methods suffer from issues such as low efficiency, high costs, significant safety risks, and delayed data, failing to meet the needs of large-scale and refined operation of the power stations. Therefore, constructing an efficient, reliable, and intelligent remote monitoring and management system has become a crucial support for the stable operation and enhanced profitability of PV power stations on abandoned mines.


 

Solution

WideIOT constructs a remote monitoring and management system for PV power stations on abandoned mines based on the "perception layer-transmission layer-platform layer" architecture, with smart energy gateways at its core, enabling comprehensive perception, stable transmission, intelligent analysis, and efficient management of the power stations.

  • Perception Layer: This layer primarily includes equipment such as PV modules, inverters, combiner boxes, battery management systems (BMS) for energy storage batteries, meteorological sensors (for light intensity, wind speed, temperature, etc.), and smart meters.

  • Transmission Layer: The smart energy gateway is compatible with protocols such as Modbus, DLT645, IEC61850, and IEC104/103/104. It interfaces with perception layer devices, collects device data, and enables internet access via 5G/4G.

  • Platform Layer: The PV power station management platform is responsible for receiving, storing, analyzing, processing, and displaying data. It provides functions such as remote monitoring, intelligent early warning, remote control, operation and maintenance management, and data analysis.

Implemented Functions

  • Centralized Monitoring via GIS Maps: Display the distribution and real-time status of PV arrays, inverters, and energy storage devices on GIS maps. Dynamically show core indicators such as power generation capacity, daily power output, and equipment utilization rates, enabling centralized monitoring of multiple power stations and devices.

  • Real-time Alerting: When abnormal equipment operation is detected, the system immediately triggers alerts and pushes notifications to management personnel through various channels such as SMS, email, and WeChat. It simultaneously marks the abnormal equipment and data, facilitating quick problem identification for management personnel.

  • Comprehensive Equipment Inventory Management: Establish a complete equipment inventory, recording information such as equipment models, specifications, installation locations, installation dates, repair records, and maintenance records. This enables full lifecycle management of the equipment, ensuring optimal performance and extending service life.

  • Automated Report Generation: Generate various operational reports, including power generation reports, power generation efficiency reports, equipment operational status reports, fault statistics reports, and inspection reports. These reports facilitate archiving, statistical analysis, and support enterprises in making informed and scientific decisions.

What is an Industrial Gateway?

  In the era of Industry 4.0, where smart factories and interconnected systems dominate,   industrial gateways   have emerged as critical components for enabling seamless communication, data exchange, and automation across diverse industrial environments. But what exactly is an industrial gateway, and why is it indispensable in modern manufacturing and process control? This article explores its definition, functions, types, and real-world applications. Definition of an Industrial Gateway An   industrial gateway   is a specialized hardware or software device designed to bridge communication gaps between incompatible industrial networks, protocols, or devices. It acts as a translator and router, ensuring that data from legacy machinery, sensors, controllers, or cloud platforms can be understood and utilized by other systems. Unlike standard networking gateways, industrial gateways are built to withstand harsh environments (e.g., extreme temperatures, v...

IoT Solution for DCS Data Acquisition of Stackers and Reclaimers

图片
  In thermal power plants, stackers and reclaimers play a crucial role in storing and conveying raw materials. They execute various automated instructions through PLCs (Programmable Logic Controllers) and DCS (Distributed Control Systems), such as allowing stacking, allowing reclaiming, peripheral reclaiming operation, emergency shutdown of stackers and reclaimers, stacking operation, stacking faults, reclaiming faults, reclaiming circuit, and more. These instructions provide reliable assistance for enhancing production efficiency and management levels. To achieve DCS data acquisition and enable remote monitoring and precise management of stacking and reclaiming operations, WideIOT offers an IoT solution based on industrial smart gateways. By connecting to the central control room’s DCS, the gateway can adapt to protocols and perform data acquisition. The collected data is then transmitted to a remote monitoring cloud platform, enabling functions such as visual display, remote moni...
