Intelligent Multi-functional Power Monitoring and Analysis Device

SHZK-PMA-9000
The SHZK-PMA-9000 is a new generation of multi-functional power monitoring and analysis device. This device integrates fault recording, dynamic disturbance recording, synchronous phasor measurement, and high-precision power quality monitoring functions. It is specifically designed to address industry challenges such as grid load surges and stable control of new energy grid integration, serving as a "fault black box" and "dynamic electrocardiograph" for ensuring the safe operation of the power grid.
This device deeply integrates five core functions: intelligent fault recording (DFR/DDR), synchronous phasor measurement (PMU), accurate fault location, real-time grid status monitoring, and in-depth fault analysis. It enables panoramic perception and intelligent diagnosis of the entire power grid process, including transient, dynamic, and steady-state states, providing users with a one-stop power grid monitoring solution and effectively reducing system deployment costs.
The product fully complies with 15 international and domestic standards and specifications, and has successfully passed type testing by national authoritative institutions. The test report is internationally recognized by CNAS and ILAC-MRA, and is valid in more than 80 countries and regions worldwide, providing highly reliable data support for the safe and stable operation of all aspects of power generation, transmission, and distribution.
1. DFR/DDR supports multiple triggering modes including over-limit, sudden change, timing, and linkage.
2. Maximum 64 analog inputs and 128 digital inputs, configurable as needed; optional 8-channel DC input acquisition.
3. PMU performs online real-time measurement and data transmission, conforming to IEC 60255-118-1-2018 and IEEE Std C37.118.2-2011 international standards.
4. Fault location error is less than 5% of the total line length, ensuring high accuracy.
5. Complies with IEEE Std C37.111-1999 standard, offering strong compatibility and compatibility with mainstream analysis software.
6. Supports time synchronization methods such as IRIG-B (optical/electrical), GPS/BDS, SNTP, and IEEE1588.
7. Synchronization accuracy is better than ±1μs, and 24-hour timekeeping accuracy is better than ±1ms.
8. Standard configuration includes 8GB solid-state storage; rolling storage prevents overflow, ensuring safety and reliability;
9. Automatic hardware fault alarms, with the faulty component displayed on the interface for quick troubleshooting.
10. Linux/Windows dual-system compatibility, graphical interface + online help for easy operation;
