Disturbance Monitoring

Analyze synchrophasor, continuous waveform, and event report data for a complete disturbance monitoring solution. Easily find system disturbances, and export data to CSV and COMTRADE data formats for NERC PRC-002-2, PRC-0028-1, and IEEE 2800 compliance. Combine Synchrowave Monitoring with SEL-5705 Synchrowave Reports software to generate automated IEEE 519 harmonic compliance reports.

Real-Time System Visibility

Improve system visibility by viewing live, subsecond, and time-aligned information from across the entire power system. Gain additional insight into the dynamic behavior of the power system through waveform signatures to aid in analysis during abnormal conditions.

Power System Model Validation

Record the system response to generator trips, load shedding, remedial action scheme (RAS) operations, and other events. Analyze the archived system responses, and compare them to power system models. Simply export system response data from Synchrowave Monitoring to external power system simulation and modeling applications.

Renewable Energy Monitoring

Gain perspective on how increasing renewable energy sources impact system stability. Dynamics from low-inertia generation sources change quickly—too fast to see at traditional SCADA rates. High-resolution measurements in Synchrowave Monitoring detect and track the impact renewables have on power quality metrics, including subsynchronous oscillation (SSO), rapid voltage change (RVC), and harmonic distortion.

Continuous Waveform Recording and Analysis

Never miss an event again. A growing line of SEL hardware provides continuous waveform streams in real time, including the SEL-2240 Axion, SEL Real-Time Automation Controller (RTAC), SEL-735 Power Quality and Revenue Meter, and soon-to-release SEL-T35 Time-Domain Power Monitor. Sampling and streaming rates range from 3 kilosamples per second (ksps) to 14.4 ksps. Synchrowave Monitoring software receives these data streams, provides real-time metering values, trends these values, provides real-time alarms, and archives the data.

Virtual Metering

View and customize a suite of power monitoring quantities. Virtual metering calculations utilize the 3.0–14.4 ksps data streams to provide power metering quantities, including voltage, current, power, frequency, symmetrical components, and power factor. Additional power quality quantities include harmonics; RVC; voltage sag, swell, and interruption (VSSI); and flicker. The virtual metering application also calculates PMU quantities with the continuous waveform data.

Synchrowave Platform

Synchrowave Monitoring includes a Microsoft Windows-based version of the Synchrowave Platform.

The platform supports installation for one server.
Synchrowave Platform applications run as Windows Services. Applications are packaged together into the Windows Installer. Updating applications individually is not supported in Synchrowave Monitoring. Installing the latest Windows installer will update all applications in the platform.

Synchrophasor Recording System Requirements

Windows OS (Windows 10 Enterprise, Windows 11, Windows Server 2016, Windows Server 2019, or Windows Server 2022 Standard)
Local storage (preferred) or high-performance network drive. Storage requirements depend on number of phasor measurement units (PMUs), number of signals per PMU, and data rate. (125 GB per PMU per year at 60 messages per second is often used for approximate storage estimates.)

Continuous Recording System Requirements

Windows OS (Windows 10 Enterprise, Windows 11, Windows Server 2016, Windows Server 2019, or Windows Server 2022 Standard)
Local storage preferred. Storage requirements depend on the number of waveform measurement devices, number of channels, and streaming rate, as exemplified below.

Model	Sample rate	Channels	Network bandwidth (Mbps)	Storage (GB per day)
SEL-735 Power Quality and Revenue Meter	3 ksps	6	1	6
SEL-2240 Axion	3 ksps	96	11	100
SEL-T35 Time-Domain Power Monitor	14.4 ksps	17	11	85
