Project Overview

Hino Systech Vietnam has successfully implemented and installed a SCADA system for the rooftop solar energy project at the Sapporo Long An plant. The SCADA software developed by Hino Systech serves as the central operational hub, providing a complete toolset for tracking, operating, and optimizing the performance of the entire solar energy system.

Comprehensive Monitoring Capabilities

The system utilizes PLC controllers to collect real-time data and transmit it to the central server. Operators can monitor granular data including power output, capacity, operational status, as well as current and voltage for each individual inverter.

• Analytics & Reporting: Automatically generates daily reports containing detailed operational parameters to evaluate power generation efficiency.

• Intelligent Alarms: Upon detecting an anomaly, the software instantly displays fault codes, root causes, and step-by-step troubleshooting instructions.

• Remote Monitoring: An intuitive and flexible web-based interface allows plant management to monitor the system from anywhere with internet connectivity.

Control & Optimization Features

Beyond monitoring, the SCADA system enables real-time PLC-based control in two modes: Automatic (Auto) and Manual. Manual mode allows operators to switch inverters on/off and actuate Air Circuit Breakers (ACBs) directly from the software interface. Crucially, the system is engineered to coordinate three power sources: the grid, solar energy, and diesel generators. During grid outages, the software automatically transitions to a combined solar-generator control scheme, maximizing fuel savings and ensuring absolute protection for the generator units.

Zero Export (Load Following) Solution

To comply with current solar power operation standards, the system incorporates Zero Export functionality. Solar generation is dynamically controlled to track the plant's actual power consumption, maximizing useful output while strictly preventing reverse power flow into the national grid.
