Synchrophasors are devices that measure the voltage, current, frequency and phase angle of electrical signals in power systems. They provide high-resolution, time-synchronized data that can be used for various applications, such as monitoring, control, protection, and optimization of power systems.


Synchrophasor technologies have been widely adopted in recent years, especially after the 2003 blackout in North America, which highlighted the need for better situational awareness and coordination in power grids. Some of the benefits of synchrophasor technologies include:

- Improving the reliability and stability of power systems by detecting and preventing disturbances, faults, and oscillations.


- Enhancing the efficiency and flexibility of power systems by enabling optimal power flow, voltage regulation, and load balancing.


- Facilitating the integration of renewable energy sources and distributed generation by providing accurate and timely information on their output and impact on the grid.


- Supporting the development of smart grids and microgrids by enabling real-time communication and control among various devices and agents.


In this blog post, we will discuss some of the main applications of synchrophasor technologies in power systems, such as:


- State estimation: Synchrophasors can provide accurate and timely information on the state of the power system, such as voltage magnitude and angle, frequency, and power flow. This can help operators to monitor the system conditions and identify any anomalies or deviations from normal operation. State estimation can also be used for contingency analysis, fault location, and restoration planning.


- Wide-area measurement system (WAMS): Synchrophasors can be integrated into a network of phasor measurement units (PMUs) and phasor data concentrators (PDCs) that collect, process, and transmit synchrophasor data to a central location. This can create a wide-area measurement system (WAMS) that provides a comprehensive view of the power system dynamics across a large geographical area. WAMS can be used for wide-area monitoring, protection, and control (WAMPAC) applications, such as oscillation detection and damping, islanding detection and prevention, adaptive protection, and emergency control.


- Frequency control: Synchrophasors can provide fast and accurate measurements of the system frequency and its variations. This can help operators to maintain the frequency within acceptable limits and to respond to frequency deviations caused by load changes or generation outages. Synchrophasors can also be used to coordinate the frequency control actions among different areas or regions of the power system, such as load shedding, generation dispatching, or automatic generation control (AGC).


- Voltage control: Synchrophasors can provide detailed information on the voltage profile and reactive power flow in the power system. This can help operators to regulate the voltage within acceptable limits and to optimize the reactive power compensation devices, such as capacitors, reactors, or static VAR compensators (SVCs). Synchrophasors can also be used to coordinate the voltage control actions among different areas or regions of the power system, such as voltage scheduling, reactive power dispatching, or automatic voltage control (AVC).


- Power quality analysis: Synchrophasors can provide high-resolution data on the harmonic content and waveform distortion of the electrical signals in the power system. This can help operators to identify and mitigate any power quality issues that may affect the performance or lifespan of sensitive equipment or devices. Synchrophasors can also be used to monitor and evaluate the impact of renewable energy sources and distributed generation on the power quality of the grid.
