Capacitor Bank Control and HMI Subsystem Reference Design for Automatic Power Factor Controller
Description
This reference design demonstrates the working of various functional blocks of an automatic power factor controller (PFC) used in MV/LV electrical distribution. This includes accurate measurement and computation of voltages: currents: power and power factor: display of measured parameters using four-digit seven-segment display: alarms and status indication using LEDs: switching outputs for driving contactor or thyristor for switching capacitor banks and monitoring of local and remote temperature using a breadth of products from our portfolio.
Features
- Accurate measurement of 3-Φ voltage: current (simultaneous sampling): power: power factor accuracy Seven segment (SS) LED – two constant current drivers are cascaded to drive four digit SS LED display with decimal pointRelay/ transistor output switching – options for controlling contactor and thyristor is provided.3 channels (expandable to 7) is dedicated for controlling relay output (contactors)2 channels (expandable to 4) with isolation for controlling transistor output (thyristors)Status indication – 16 LEDs are controlled using a constant-current LED sink driver.Sensors for temperature and light sensing are included.
