Local controls Flashcards
How do you define a local control for AC block?
local controller provides control and protection for pairing of PCS with battery pack. The PCS may have sub PCS within itself controlled by PCS controller. One local control device per power dispatch interface.
Various states for LC
Ready, Starting, Running (PQ), Stopping, Faulted, Standby, Running (VF), Running (DC current command), Comm Loss, Unkown
Various operational modes
Manual, Auto, Maintenance
Describe Start state
Transition unit from ready state to standby or running
Describe Stop state
Transition unit from running/standby to stopped/ready state
Describe Reset state
Rest all fault and alarms
Describe Running state
send manual active or reactive power dispatch commands
LC manual mode
Transition LC to manual mode
Descriibe Auto mode
Transition unit to auto mode
Describe maintainence mode
Transition LC to maintenance mode
Describe starting battery - troubleshooting
Transition battery only from stopped state to running state
Describe stop battery state - troubleshooting
Transition battery system only from running state to stop state
Describe pre-charge state - troubleshooting
Start battery pre-charge routine
Reset battery system - troubleshooting
clear all fault and alarms in BMS
Start, stop, reset, and initialize PCS states
only for troubleshooting
