Acrel APView350: Your Guardian of Power Quality for New Energy Grids
New energy power stations are equipped with online power quality monitoring devices, whose core purpose is to address four major issues: grid connection compliance, equipment safety, power generation revenue, and power grid stability. Amid the rapid development of new energy power generation systems such as photovoltaic (PV), energy storage, and wind power, PV/wind power output fluctuates rapidly due to changes in sunlight and wind speed, directly leading to voltage deviations, frequency fluctuations, flicker, and harmonics. Power grid companies impose strict limits on harmonics, voltage deviations, three-phase imbalance, and other parameters—without monitoring, compliance cannot be proven. A large number of power electronic devices generate harmonics, causing cable overheating, abnormal transformer noise, protection maloperations, and shortened equipment lifespans. Instantaneous voltage anomalies can trigger inverter grid disconnection, directly reducing power generation and causing economic losses. Power quality monitoring for 10kV and below distribution networks has become critical to ensuring stable power grid operation.
The Acrel APView350 Online Power Quality Monitoring Device is built around a high-performance multi-core platform, running an embedded Linux system. It features high-precision sampling with 1024 points per cycle and 32GB industrial-grade storage, perfectly meeting the monitoring needs of new energy scenarios. The device can record fault waveforms and locate disturbance sources, enabling quick troubleshooting and recovery for operation and maintenance teams. It also accumulates historical data for efficiency analysis, technical transformation planning, and power station valuation.
Integrating multiple functions such as harmonic analysis, voltage sag/swell monitoring, flicker detection, and energy metering, the Acrel APView350 meets Class A accuracy standards as specified in national standards, accurately capturing various power quality issues including voltage deviations, frequency fluctuations, and inter-harmonics. With abundant interface resources supporting multiple communication protocols such as Modbus and IEC61850, the device allows on-site data viewing via a local LCD screen and remote convenient management through its WebServer function. It also offers specialized features like voltage sag/swell source localization and ITIC/SEMI F47 tolerance analysis, providing scientific evidence for fault troubleshooting and mitigation.
Comprehensive self-checking of hardware and software, along with stringent electromagnetic compatibility certifications, ensures the device operates stably in complex industrial environments. Whether for grid connection monitoring in new energy power stations or distribution network management in industrial enterprises, the APView350 is a reliable choice for power quality monitoring, building a solid defense line for safe and efficient power grid operation.
