8BCONTROL FUNCTIONS
PROTECTION, CONTROL AND METERING FUNCTIONS
Figure 2-73 General diagram of the control algorithm of capacitor banks
The smART P500 BC protective relay has the following operation modes:
Reactive Flow
: Switching of Capacitor Bank depends on the values of reactive
power flow
Clock:
Switching of Capacitor Bank depends on the level of measured voltage
and the programmed time schedule
2.8.5.2. REACTIVE FLOW CONTROL TYPE
In case of three-pole breakers, it is used the value of total reactive power, while for
single-pole ones, it is used the value of the reactive power of each phase being
processed.
