Multiway switching : 

In building wiringmultiway switching is the interconnection of two or more electrical switches to control an electrical load (often, but not always, lighting) from more than one location. For example, this allows lighting in a hallway, stairwell, or large room to be controlled from multiple locations. While a "normal" light switchneeds to be only a single pole, single throw (SPST) switch, multiway switching requires the use of switches that have one or more additional contacts and two or more wires must be run between the switches. When the load is controlled from only two points, single pole, double throw (SPDT) switches are used. Double pole, double throw (DPDT) switches allow control from three or more locations.

By connecting one or more 4-way (intermediate) switches in-line, with 3-way switches at either end, the load can be controlled from three or more locations. Toggling any switch changes the state of the load from off to on, or from on to off.

AC motor :


Operating principles :
When an AC motor is in steady-state rotation (motion), the magnetic fields of the rotor and stator rotate (move) with little or no slippage (near synchrony). The magnetic forces (repulsive and attractive) between the rotor and stator poles create average torque, capable of driving a load at rated speed. The speed of the stator rotating magnetic field (\omega_s) and the speed of the rotor rotating magnetic field (\omega_r), relative to the speed of the mechanical shaft (\omega_m), must maintain synchronism for average torque production by satisfying the synchronous speed relation (i.e., \pm\omega_s \pm\omega_r = \omega_m).[1] Otherwise, asynchronously rotating magnetic fields would produce pulsating or non-average torque.
The two main types of AC motors are classified as induction and synchronous. The induction motor (or asynchronous motor) always relies on a small difference in speed between the stator rotating magnetic field and the rotor shaft speed called slip to induce rotor current in the rotor AC winding. As a result, the induction motor cannot produce torque near synchronous speed where induction (or slip) is irrelevant or ceases to exist. In contrast, thesynchronous motor does not rely on slip-induction for operation and uses either permanent magnets, salient poles (having projecting magnetic poles), or an independently excited rotor winding. The synchronous motor produces its rated torque at exactly synchronous speed. The brushless wound-rotor doubly fed synchronous motor system has an independently excited rotor winding that does not rely on the principles of slip-induction of current. The brushless wound-rotor doubly fed motor is a synchronous motor that can function exactly at the supply frequency or sub to super multiple of the supply frequency.
Other types of motors include eddy current motors, and also AC/DC mechanically commuted machines in which speed is dependent on voltage and winding connection.

Servo drive :
servo drive is a special electronic amplifier used to power electric servomechanisms.

A servo drive monitors the feedback signal from the servomechanism and continually adjusts for deviation from expected behavior.

Function :
A servo drive receives a command signal from a control system, amplifies the signal, and transmits electric current to a servo motor in order to produce motion proportional to the command signal. Typically, the command signal represents a desired velocity, but can also represent a desired torque or position. A sensor attached to the servo motor reports the motor's actual status back to the servo drive. The servo drive then compares the actual motor status with the commanded motor status. It then alters the voltage frequency or pulse width to the motor so as to correct for any deviation from the commanded status.
In a properly configured control system, the servo motor rotates at a velocity that very closely approximates the velocity signal being received by the servo drive from the control system. Several parameters, such as stiffness (also known as proportional gain), damping (also known as derivative gain), and feedback gain, can be adjusted to achieve this desired performance. The process of adjusting these parameters is called performance tuning.
Although many servo motors require a drive specific to that particular motor brand or model, many drives are now available that are compatible with a wide variety of motors.

Use in industry :

Servo systems can be used in CNC machining, factory automation, and robotics, among other uses. Their main advantage over traditional DC or AC motors is the addition of motor feedback. This feedback can be used to detect unwanted motion, or to ensure the accuracy of the commanded motion. The feedback is generally provided by an encoder of some sort. Servos, in constant speed changing use, have a better life cycle than typical AC wound motors. Servo motors can also act as a brake by shunting off generated electricity from the motor itself.










Variable-frequency drive :


variable-frequency drive (VFD) (also termed adjustable-frequency drivevariable-speed drive,AC drivemicro drive or inverter drive) is a type of adjustable-speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequencyand voltage.

SCADA architectures :

First generation:Monolithic

Second generation: Distributed

Third generation: Networked

Fourth generation: Internet of Things

With the commercial availability of cloud computing, SCADA systems have increasingly adopted Internet of Things technology to significantly reduce infrastructure costs and increase ease of maintenance and integration. As a result, SCADA systems can now report state in near real-time and use the horizontal scale available in cloud environments to implement more complex control algorithms than are practically feasible to implement on traditional programmable logic controllers.[13] Further, the use of open network protocols such asTLS inherent in the Internet of Things technology, provides a more readily comprehensible and manageable security boundary than the heterogeneous mix of proprietary network protocols typical of many decentralized SCADA implementations. One such example of this technology is an innovative approach to rainwater harvesting through the implementation of real time controls (RTC).

Human–machine interface :


An important part of most SCADA implementations is alarm handling. The system monitors whether certain alarm conditions are satisfied, to determine when an alarm event has occurred. Once an alarm event has been detected, one or more actions are taken (such as the activation of one or more alarm indicators, and perhaps the generation of email or text messages so that management or remote SCADA operators are informed). In many cases, a SCADA operator may have to acknowledge the alarm event; this may deactivate some alarm indicators, whereas other indicators remain active until the alarm conditions are cleared. Alarm conditions can be explicit—for example, an alarm point is a digital status point that has either the value NORMAL or ALARM that is calculated by a formula based on the values in other analogue and digital points—or implicit: the SCADA system might automatically monitor whether the value in an analogue point lies outside high and low- limit values associated with that point. Examples of alarm indicators include a siren, a pop-up box on a screen, or a coloured or flashing area on a screen (that might act in a similar way to the "fuel tank empty" light in a car); in each case, the role of the alarm indicator is to draw the operator's attention to the part of the system 'in alarm' so that appropriate action can be taken. In designing SCADA systems, care must be taken when a cascade of alarm events occurs in a short time, otherwise the underlying cause (which might not be the earliest event detected) may get lost in the noise. Unfortunately, when used as a noun, the word 'alarm' is used rather loosely in the industry; thus, depending on context it might mean an alarm point, an alarm indicator, or an alarm event.

SCADA : Supervisory Control And Data Acquisition

SCADA (Supervisory Control And Data Acquisition) is a system for remote monitoring and control that operates with coded signals over communication channels (using typically one communication channel per remote station). The control system may be combined with a data acquisition system by adding the use of coded signals over communication channels to acquire information about the status of the remote equipment for display or for recording functions.[1] It is a type of industrial control system (ICS). Industrial control systems are computer-based systems that monitor and control industrial processes that exist in the physical world. SCADA systems historically distinguish themselves from other ICS systems by being large-scale processes that can include multiple sites, and large distances.[2]These processes include industrial, infrastructure, and facility-based processes, as described below:

AUTOMATION OF WATER TREATMENT PLANT :


Over the years the demand for high quality, greater efficiency and automated machines has increased in the industrial sector of water treatment plants. Water treatment plants require continuous monitoring and inspection at frequent intervals. There are possibilities of errors at measuring and various stages involved with human workers and also the lack of few features of microcontrollers. PLC applications are extensively used in industry to control and facilitate repetitive process such as furnace, bottle filling plants, elevator systems or nuclear plant shutdown systems. One of these applications in industrial automations which include numerous automated processes. This includes automation of water treatment plant using PLC. Controlling high pressure is critical task, so here automation plays vital role. There are many fields where pressure and water level control need to be done simultaneously. Thus it becomes tedious job to handle the product manually and also processing time may vary due to human handling errors. This might not give expected results. Thus automation plays an important role in this process. Automation rectifies the human errors, increase the repeatability and accuracy of the system and decrease time consumption.

C. Reverse Osmosis: It is a purification process that requires special equipment. The system consists of a two-part tank that is separated by a membrane. Untreated water enters the tank on one side and is forced through the membrane. The membrane allows clean water to filter through while holding back contaminants. The treated water enters the second half of the tank and then is collected and stored for consumption.D. Ultraviolet Light: In this method, water is placed in a clear container and then subjected to ultraviolet light, which destroys harmful organisms in the water. One of the drawbacks to this method is the power required to generate UV light. If insufficient UV light is applied to the water, it may not kill the organisms. The process depends on numerous factors, including the amount of water being purified, the initial condition of the water, and the size and intensity of the light.
