Load Frequency Control with Generation Rate Constraint (GRC): Load Frequency Control with Generation Rate Constraint (GRC) - The Load frequency Control problem discussed so far does not consider the effect of the restrictions on the…
Data Acquisition System: A typical Data Acquisition System consists of individual sensors with the necessary signal conditioning, data conversion, data processing, multiplexing, data handling and associated transmission, storage and display systems. In order to optimise…
Multistage Impulse Generator Circuit: In the early discussion, the generator capacitance C1 is to be first charged and then discharged into the wave shaping circuits. A single capacitor C1 may be used for voltages up…
Field Diverter Method of Speed Control of DC Series Motors: The field flux can be reduced by shunting a portion of motor current around the series field, thus reducing the excitation mmf and weakening of…
Moving Iron Instrument | Types of Moving Iron Instruments: Moving Iron Instrument can be classified into attraction and repulsion types. Repulsion type instruments are the most commonly used. Iron vane ammeters and voltmeters depend for…
Short Circuit Current in Synchronous Generator: The Short Circuit Current in Synchronous Generator being electrical in nature is much faster than the electromechanical dynamics discussed already. It will, therefore, be assumed that by the time…
Testing of Overcurrent Relay: Test benches are used for proving the design characteristics of relays. These are provided with accurate timing apparatus and calibrated current and voltage supplies. The basic circuit for Testing of Overcurrent…
Frequency Domain Analysis: Frequency Domain Analysis - As we now already, the responses of the networks to the various time dependent inputs such as step, ramp, exponential etc. are studied. Let us now discuss the…
Gas Actuated Relays: Gas Actuated Relays - When a fault occurs inside the transformer tank gas is usually generated, slowly for an incipient fault and violently for heavy faults. Most short circuits developed either by…
Positive High Voltage High Current Regulator: Positive High Voltage High Current Regulator - For this type, output voltage from +7V to +37V and load current IL > 150 mA. For this a external transistor Q1Â is…
