How does reactive power linked with system stability?
Currently going through study of reactive power management, I find myself in doubt that is if the reactive power goes down in a system. First case is that it will deteriorate the voltage profile and hence the transmission line can trip on undervoltage protection, leading to overvoltage of other lines, but other case what I look for is that if reactive power will reduce that will lead to more generation of active power that will increase in the current which will create failure of insulation like problem ultimately tripping of power plant.
I would like to give your valuable comments on my thinking and provide me with right direction if I am wrong...
