“…The difference between the highly stabilized reference and the actual value is amplified in different stages of amplification. Three Current Transformers senses the output current of the Alternator, feed proportional current across variable resistors in the AVR [6]. The voltage thus obtained across the resistors, can be added vectorially either for compounding or for transformer drop compensation.…”

Logic control of Static Excitation System (SES) in Power Alternators deals with the use of PLC to control the terminal output voltage of the Alternator in a more simplified and efficient manner using a closed loop system. A closed loop control with negative feedback is designed, which involves AVR, Pulse Generator, Pulse Amplifier, Limiters, Power System Stabilizers with an Auto and a Manual channel. Disruption in the terminal voltage is caused by faults. These faults were rectified earlier by Electro Mechanical relays. Now we are at a major technological Change of Analog to Digital control. It reduces the complexity of the control system, and eliminates the need of wide range of contactors and coils to energies the relay. The best way to maintain the stability of the system is to identify the need and rectify it. This paper proposes an easy and an efficient design for fault detection and elimination using PLC based excitation system in power alternators.

With the increasing capacity of photovoltaic (PV) power plants connected to power systems, PV plants are often required to have some reactive power control capabilities to participate in reactive power regulation. Reactive power regulation of grid-connected PV inverters can be achieved using different control strategies. In this paper, the reactive power capability of inverters and the technical requirement of PV plants are analyzed. The reactive power capability of a 30 MW PV plant is evaluated against relevant technical standards using a new testing method proposed in this paper.
