Abstract:

<p>Excitation system is a system that conducts electric current in the same direction as a generator in a power plant, so that it produces electricity and a large voltage on the increase in the excitation current. In modern regulatory systems, excitation plays an important role in controlling the stability of a development because it involves load fluctuations, so excitation as a controller will require control of the generator output such as voltage, current and power factors in a necessary manner. If the excitation current rises, the reactive power supplied by the system generator will

Abstract — The output voltage changes at any time up or down will have an effect such as damage to generator components to overcome the instability of the voltage produced by the generator, a device is needed to regulate the excitation current, namely the Automatic Voltage Regulator (AVR) which works on the exciter, if the load decreases, the AVR will instruct the exciter to reduce the excitation current.

Abstract:

The main objective of this PIC-based excitation control system is to control the terminal voltage by adjusting the generator exciter voltage. Unlike the conventional control system, the PIC-based excitation control system is constructed to reduce the number of components and thus the amount of design work and wiring required for the system. As a consequence, this is constructed to be low cost and high performance. In this work, this design is based on the construction of switched mode power supply (SMPS).

Abstract:

The generator in the hydropower system is used to convert mechanical energy originating from the turbine rotation into electrical energy by producing an electromotive force. Excitation is one of the most crucial parts of the Generator system, where excitation plays a role in forming/producing electromagnetic flux, resulting in an induced emf. The amplifying current is used to adjust the magnitude of the output voltage according to the applied load. The tool used to regulate the excitation current is the Automatic Voltage Regulator (AVR).

Modern operating conditions of large industrial enterprises require the provision of high reliability of power supply to consumers while reducing the cost of the electricity consumed. These requirements are ensured by the widespread introduction of own sources of electrical energy. These include combined heat and power plants, gas turbines, gas pistons and steam and gas power plants. At the same time, there is a significant complication of the industrial network configuration and possible emergency modes. One of the emergency modes in such networks is the loss of excitation of the synchronous
