BE190 IEC104 Edge I/O Module addresses these challenges by providing standardized protocol conversion and reliable remote dispatch capabilities.
Case Details
With the rapid growth of renewable energy generation, grid operators require real-time monitoring of photovoltaic (PV) power plant data (e.g., power output, voltage, current) to ensure grid stability. Traditional data acquisition methods often suffer from poor protocol compatibility and insufficient real-time performance. The BLIIOT BE190 IEC104 Edge I/O Module addresses these challenges by providing standardized protocol conversion and reliable remote dispatch capabilities.
Device Selection
- Host Model: BE190 IEC104 Edge I/O Module
- Y1 Board: Y31 (4CH Analog Input Module): Collects 4-20mA current signals from inverters.
- Y2 Board: Y51 (2CH RTD Input Module): Monitors transformer temperature (PT100 sensors).
- Y3 Board: Y13 (8CH Dry Contact Input Module): Receives fault alarms from PV arrays.
Network Architecture
- The BE190 connects to the PV plant's local network via dual Ethernet ports, communicating with inverters, weather stations, and transformers via Modbus RTU.
- Data is converted to IEC104 protocol and transmitted to the grid dispatch center
Implementation Steps
- The BE190 RS485 port (Modbus Master mode) reads real-time generation data (e.g., DC voltage, AC power) from inverters.
- Analog input modules (Y31) collect transformer temperature, while RTD modules (Y51) monitor ambient conditions.
- The BE190 maps Modbus data to standard IEC104 information objects (e.g., ASDU Type 13, 21) with timestamps and quality flags.
- IEC104's balanced communication mode (TCP port 2404) ensures periodic reporting (e.g., every 2 seconds) and supports auto-reconnection and retransmission for reliability.
- Engineers can remotely configure parameters, update firmware, or troubleshoot via the web interface or BLRAT (Belial Remote Access Tool).
Key Advantages
- High Reliability: Certified for -40°C to 85°C operation and compliant with EMC/EMI standards, ensuring stable performance in harsh environments.
- Real-Time Performance: IEC104 supports millisecond-level data transmission, meeting grid dispatch requirements.
- Flexible Expansion: Optional I/O modules adapt to various PV equipment (e.g., string inverters, central inverters).
- Regulatory Compliance: Fully compliant with IEC 60870-5-104, ensuring seamless integration with grid master stations.
