چکیده
This paper presents the two basic comparison techniquesThe amplitude and phase comparisons, used in power system protection and control. Phasor diagrams were used to discuss their relationships and circuit diagrams were modeled for the description of their operations. The general expression for impedance, Mho, positive offset and negative offset Mho characteristics were developed. At a stage simulation was done on a phase comparator to obtain the required characteristic.

متن کاملApplication of ANN Technique for Interconnected Power System Load Frequency Control (RESEARCH NOTE)
This paper describes an application of Artificial Neural Networks (ANN) to Load Frequency Control (LFC) of nonlinear power systems. Power systems, such as other industrial processes, have parametric uncertainties that for controller design had to take the uncertainties in to account. For this reason, in the design of LFC controller the idea of robust control theories are being used. To improve ...

In recent years several catastrophic power systems blackouts have occurred worldwide. Various reasons have been declared for these failures. Economical limitations due to power system restructuring restrictions, inadvertent operation of protective relays and inefficient design of conventional load shedding schemes are of the most important reasons causing these blackouts. In fact, due to both e...
متن کاملSimultaneous power sharing and protection against faults for DGs in microgrid with different loads
The LVRT (Low Voltage Ride Through) is the main characteristic of every power system in faulty conditions. When fault occurs, it is essential for power system such as microgrid to control the voltage and frequency normally. Naturally in fault status, the unbalanced voltage and current are inevitable, but with the aid of LVRT technique, microgrid can keep stability in main system parameters such...
