power quality improvement of power system network using UPFC
This document presents a project on improving power quality in a power system network using a Unified Power Flow Controller (UPFC). It defines power quality and discusses causes of poor power quality such as non-linear loads and switching operations. It then introduces Flexible AC Transmission Systems (FACTS) devices as a way to improve power quality and lists benefits such as increasing power transfer capability and improving transient stability. Specifically, it describes a UPFC, which combines a static synchronous compensator (STATCOM) and static synchronous series compensator (SSSC) to independently control real and reactive power flow. The UPFC configuration and components are shown, and it is explained how the UPFC can improve power quality by regulating voltage, impedance

Overview of Microgrids
A microgrid is a group of interconnected loads and distributed energy resources that can operate connected or disconnected from the main power grid. Microgrids provide benefits like reducing outage effects, optimizing demand and costs, integrating distributed resources, and improving asset management. They are well-suited for locations that experience frequent outages and have potential distributed energy resources like solar, enabling independence from the main grid during emergencies. The document discusses factors to consider for microgrid location and implementation, citing examples in Massachusetts.

A three phase transformer is made of three sets of primary and secondary windings wound around the legs of a common iron core. It allows for higher transmission voltages using lower amperage wiring. The core can be constructed as either a core type or shell type configuration. A three phase transformer works by inducing secondary voltages from the three phase primary voltages to maintain the proper phase relationships for power distribution.

Multi level inverter
A multilevel inverter converts DC voltage to AC voltage using multiple lower level DC voltages as inputs. It produces a stepped staircase waveform that is closer to a sinusoidal waveform compared to a conventional inverter. This project generates AC sinusoids up to multilevel levels by comparing a 2-level inverter to the developed multilevel inverter. The goal is to produce a smooth sinusoidal voltage for appliances by using multiple switching levels to reduce voltage changes.
Sumpner Test on Transformers
The document discusses the Sumpner's test, which is used to test large power transformers without actual loading. It has the following key points:
1. The Sumpner's test connects two identical transformers back to back, with their primaries in parallel and secondaries in series opposition, allowing them to be tested at full load conditions while only supplying power for losses.
2. This configuration causes the induced voltages in the secondaries to oppose each other, resulting in no net current flow between them. An auxiliary transformer is used to induce current and measure copper losses.
3. The test accurately determines total losses as they would occur in actual use, allowing efficiency and regulation to be found without full loading.

Per unit system
Per unit analysis is used to normalize variables in power systems to avoid difficulties in referring impedances across transformers. It involves choosing base values for voltage, power, impedance and current, then expressing all quantities as ratios of their actual to base values. This allows transformer impedances to be treated as single values regardless of which side they are referred to. It also keeps per unit quantities within a narrow range and clearly shows their relative values. The procedure is demonstrated through an example circuit solved first using single phase and then three phase per unit analysis with the same result.

1) Charles Flynn developed a magnetic frame device that uses coils wound around an iron frame containing a powerful permanent magnet. Applying pulses to the coils can produce linear or circular motion without moving parts.
2) Lawrence Tseung created a similar magnetic frame device that inserts a permanent magnet into one arm. Applying sharp DC pulses to a coil on one side can produce over-unity output power from a coil on the other side if the pulses reinforce the magnet's field.
3) Thane Heins developed a figure-eight double toroid transformer that can produce over 30 times the input power. The unique magnetic flow paths allow most reverse magnetic flux to cancel out, greatly improving efficiency over standard transformers.
BUSBAR PROTECTION
Busbar protection uses differential protection to isolate faults on the busbar. It works by comparing the current entering and leaving the busbar using CTs - any difference indicates an internal fault. Proper CT ratios and a stabilizing resistance are needed to restrain operation for external faults. PS class CTs are preferred over other classes due to more consistent accuracy. While busbar protection is important, it is currently not implemented in line at MRSS due to some unspecified reason.

voltage stability
This document discusses improving voltage stability in power systems by compensating for reactive power. It explains that voltage instability can be caused by heavy loads drawing high reactive power, generators being far from loads, and low source voltages. Reactive power compensation devices like shunt capacitors and SVCs are effective ways to control voltage levels by managing reactive power production, absorption, and flow. Shunt capacitors and SVCs are discussed in more detail, including their advantages and disadvantages for providing reactive power compensation.
Automatic DC strarters
The document describes two types of automatic DC starters: back EMF starter and time delay starter. The back EMF starter cuts resistance out of the circuit as the motor's speed increases by using the back EMF to energize coils. The time delay starter cuts resistance at set time intervals using time delay coils to close contacts and bypass sections of resistance. Both starters limit current and protect the motor during starting by adding resistance to reduce current until the motor is up to speed.

UNIVERSAL MOTOR.pptx
Universal motors can operate on both AC and DC power supplies. They have series-wound armatures and field windings which allow them to generate high torque. On DC power, they run at a higher speed than on AC power of the same voltage due to reactance voltage drop. They consist of a stator with field poles and coils, and an armature made of skewed slots housing a commutator and brushes. Regardless of the power source, the motor produces torque in the same direction through synchronized reversal of the magnetic field and armature current. Universal motors are compact and lightweight but noisy, with efficiencies around 30% for smaller models. They are commonly used in appliances requiring variable speed control like fans,

Viii shear and diagonal tension
1. Shear and diagonal tension are two failure modes of reinforced concrete beams. Shear failure occurs when the shear stresses exceed the shear capacity of the beam. Diagonal tension failure occurs due to cracking along a diagonal plane.
2. Shear stresses can be calculated using equilibrium equations that relate applied shear, shear capacity, and section properties. The shear capacity is generally limited to less than 1.5 times the square root of the concrete compressive strength.
3. Shear reinforcement such as stirrups or bent bars is used to improve the ductility and increase the shear capacity of beams subjected to high shear stresses. Codes specify minimum shear reinforcement ratios to prevent brittle shear failures.
