Combine the power of synchrophasor message processing with flexible programmable logic for wide-area protection and control applications. The Synchrophasor Vector Processor (SVP), the first real-time synchrophasor programmable logic controller, collects synchrophasor messages from relays and phasor measurement units (PMUs). The SVP time-aligns incoming messages, processes them with an internal logic engine, and sends control commands to external devices to perform user-defined actions. Additionally, the SVP can send calculated or derived data to devices such as other SVPs, phasor data concentrators (PDCs), and monitoring systems. |
- Identify oscillatory conditions with preconfigured
modal analysis.
- Measure system phase angles, voltages, currents,
and real/reactive power.
- Improve system efficiency by minimizing loop flow,
optimizing voltages, and balancing loads.
- Control circuit breakers, static VAR controls (SVCs),
generators, and other devices with wide-area-based
algorithms.
The SEL-3378 Synchrophasor Vector Processor closes the control loop between the power system and wide-area measurements.

Detect Instability With Preconfigured Modal Analysis Function Block
Close a contact based on critical stability indicators, such
as oscillatory frequency and damping ratio, to assess
power system health. Analyze up to 15 different modes
from up to six different input voltages, currents, or
real/reactive power. Detect unstable operating conditions,
or check model predictions.
Base alarms on mode amplitude, frequency, damping
constant, and ratio for direct alarm or in combination
with other conditions.
