Disturbance Monitoring—Analyze archived synchrophasor data and relay event reports together in one display for a complete disturbance monitoring solution. Easily find system disturbances, and export data to CSV and COMTRADE data formats for NERC PRC-002-2 compliance.

Renewable Energy Monitoring—Understand how the increasing amount of renewable energy being added to your grid impacts system stability, and detect new oscillatory modes that may be inadvertently introduced. System dynamics from these generation sources change quickly—too fast to see at traditional SCADA rates. Use high-resolution displays in synchroWAVe Central for detection and tracking of the impact of renewables on your system.

Oscillation and Disturbance Detection—Improve power system stability by investigating oscillations and disturbances detected by synchroWAVe Central. The high-resolution phasor measurement unit (PMU) measurements enable algorithms to automatically detect anomalies in the power system. synchroWAVe Central provides immediate email notification to alert engineers and operators of newly detected oscillations and disturbances. Alerts provide trends and disturbance levels in order to quickly determine the location and impact.

Power System Model Validation—Record the system response of generator trips, load shedding, remedial action scheme (RAS) operations, or other events. Analyze the archived system responses, and compare them to power system models. Simply export system response data from synchroWAVe Central to external power system simulation/modeling applications.

See Live Synchrophasors

Coming soon! SEL is streaming synchrophasor measurements to SEL-5703 Synchrowave Monitoring and SEL-5702 Synchrowave Operations software from PMUs around the United States measuring wall outlet data. The live stream is being set up and will be available soon.

    1. 1

      Automatically Detect Disturbances

      Algorithms in synchroWAVe Central automatically detect disturbances and oscillations in real time and with historical data, quickly providing operators and engineers new insights into their system performance.

    2. 2

      Determine the Disturbance Location

      Possible disturbance locations are listed by measured impact, providing operators and engineers the information needed to determine the location. The top three phasor measurement units (PMUs) in this example were located in a substation next to a solar farm.

    3. 3

      Understand the Impact

      Frequency bins provide a representation for the type of disturbance or oscillation detected. A high frequency may point to a solar or wind farm, whereas a lower frequency may represent a more traditional generation source.

    4. 4

      Receive Automatic Notifications

      Alarms and email alerts provide automated notification during a significant system disturbance.



synchroWAVe Central provides viewing and analysis of both real-time and historical synchrophasor data and allows operators and engineers to seamlessly switch between these two modes. synchroWAVe Central archives all incoming synchrophasor data, so engineers and operators can view past events on the system. This archived information helps engineers and operators determine the root cause and order of operation. Synchrophasor visualization tools provide a level of detail not possible at SCADA data rates.

Automated Oscillation and Disturbance Detection
Quickly analyze power system oscillations and disturbances automatically detected by synchroWAVe Central. For each detected oscillation and disturbance, information is provide to help operators and engineers determine the location and impact. Email notification of detected disturbances keeps everyone informed of current events on the power system.

Configurable Alarms
Configure alarms with both warning and alert thresholds. Selecting an asserted alarm provides a trend of the signal with alarm limits so operators can easily determine the current state of the system.

Geographic Map
The geographic map provides an early warning system for disturbances on the grid. Upon setup, operators can define the regions, devices, and interconnecting locations they would like displayed. The geographic map displays voltage magnitude contours in addition to angle differences and power flow between key PMU locations, providing operators and engineers with a system-wide view at a glance.

Chart Trending
synchroWAVe Central charts can display frequency, voltage, current, power, analog, and digital signals for trended analysis over time to obtain a more detailed understanding of the event. Operators and engineers can zoom in on various parameters for an in-depth view of the system response.

Quickly find similar events that meet your specified criteria. For example search for underfrequency events that have occurred over the past month to determine if there are commonalities between past events.

Export Data
Send data to others for analysis or export the data to another application. All data shown on the display can be exported using the “Data Export” button. The archived system response to a generation trip can be exported for comparison to model responses for validation. Similar analysis is possible for capacitor switching, load shedding, or other significant power system events.

Save and Share Snapshots
Save and share events of interest with colleagues for analysis at a later time. Saving and comparing similar events helps identify potential areas of weakness and hidden failure modes in the system. All snapshots are saved permanently in the database.

Role-Based Access
Authenticate and manage operator and engineer access by assigning roles. Microsoft Active Directory is supported for authentication.

Automatic Failover
Implement a fully redundant system with automatic failover to ensure that application downtime is minimized during server failures, communication failures, and software upgrades.

Phasor Scope
Compare real-time and historic phase angles across the power system easily with the phasor scope. Phase angle visibility is also valuable when synchronizing generation unit to the power system.

Event Timeline
Display relay event reports as they are collected with acSELerator Team Software for near-real-time analysis of protective relay operation. Summary information, such as the fault location and fault type, are available to the operator. Engineers can also dig deeper by analyzing the relay oscillography with the integrated synchroWAVe Event 2015 Software.

Bar Chart
Visualize power and voltage levels in real time from across the power system for greater situational awareness.

Modal Analysis
Monitor power system modes in real time and in history. Detect growing oscillations on the power system by monitoring the damping ratio of the mode.

synchroWAVe Central offers two licensing options to meet your synchrophasor visualization needs: Disturbance Monitoring and Wide-Area Situational Awareness (WASA). The Disturbance Monitor license feature set contains all the tools you need for basic viewing, archiving, and analysis of real-time and historical synchrophasor data. The WASA license feature set includes additional functionality necessary for operations control centers. For these, the WASA feature set provides operators with real-time association of measurements with overall system health and minimal susceptibility to network or server failure. SEL recommends the new Synchrowave Operations software for situational awareness use cases.
