An Improved Nonlinear STATCOM Control for Electric Arc Furnace Voltage Flicker Mitigation
Abstract
Electric arc furnaces (EAFs) are prevalent in the steel industry to melt iron and scrap steel. EAFs frequently cause large amplitude fluctuations of active and reactive power and are the source of significant power-quality (PQ) disturbances. Static synchronous compensators (STATCOMs) provide a power-electronicbased means of embedded control for reactive power support and PQ improvement. This paper introduces a new nonlinear contr ....etc

plc elevator ladder logic example pdf

On modern elevators the control logic is PLC based, probably because relays are more expensive than electronic components. Besides a PLC makes simple the electrical connections and reduces the chance of failure. On old elevators the direction of the car is controlled by selectors mounted in the shaft, one at each floor. On modern elevators there may be one impulse switch only, mounted on the top of the car. When the elevator moves the impulse switch detects a sequence of magnets placed in the shaft, then s ....etc

AUTOMATIC TEMPERATURE CONTROL IN VACUUM BRAZING FURNACE USING P.L.C

ABSTRACT
The main objective of this project is to maintain & control temperature uniformly of the two zones in vacuum brazing furnace and braze similar or dissimilar components using certain chemicals, for the given specifications of a job
Brazing alloys used for brazing the components of gas turbines and aerospace applications contain nickel as the base material. Nickel has highest affinity for oxygen. Incase if components are brazed using nickel ....etc

Vaccum Brake System
The vacuum brake is a braking system employed on trains and introduced
in the mid-1860s. A variant, the automatic vacuum brake system, became
almost universal in British train equipment and in those countries influenced
by British practice. Vacuum brakes also enjoyed a brief period of adoption
in the USA, primarily on narrow gauge railroads. However, its limitations
caused it to be progressively superseded by compressed air systems starting
in the United Kingdom from the 1970s onward. The vacuum brake system is ....etc

The project is designed to automatically operate an electric bell several times as required in an educational institution like school or college. It overcomes the difficulties of switching the bell on/off manually. This proposed system has an inbuilt real time clock (RTC) to keep a track of the time and thus to switch on/off the load accordingly.

The project uses a real time clock (RTC DS1307) interfaced with the microcontroller of the 8051 family. While the set time equals to the real time, the microcontroller gives command to the correspon ....etc
