I want to know following things for turbogenerator synchronization.
1- When we say phase angle should be within limit we talk about RYB phase of generator and bus to be connected? So we take only one phase like RR or YY or all?
2-Suppose 3 210MW generators are there. After islanding when once again we go for synchronization with grid, once we synchronize one unit say unit-2 what precaution to be taken for U-1 or U-3 synchronization as we are already with grid? During U-2 synchronization we synchronize with grid side breaker as in islanding generator circuit breaker is already in closed position?
