The document discusses mathematical tools for analyzing periodic and aperiodic signals related to electrical grids. It describes how electrical grid assets produce both periodic signals, like voltage oscillations at 50-60 Hz, as well as aperiodic signals from sensor measurements of various asset parameters. A wide range of sensing technologies monitor these parameters. For periodic signals, tools like Fourier analysis are appropriate. Aperiodic signals require tools designed for non-repeating signals, such as wavelet analysis, nonlinear dynamic analysis, and time history analysis. A variety of signals must be analyzed, so no single technique applies to every use case.

AUTOMATIC VOLTAGE CONTROL OF TRANSFORMER USING MICROCONTROLLER AND SCADA
LABVIEW PROJECT FINAL YEAR EEE
ABSTRACT: A tap changer control operates to connect appropriate tap position of winding in power transformers to maintain correct voltage level in the power transmission and distribution system. Automatic tap changing can be implemented by using µC. This improved tap-changing decision and operational flexibility of this new technique make it attractive for deployment in practical power system network. This paper deals with the implementation of µC based tap changer control practically, using special purpose digital hardware as a built-in semiconductor chip or software simulation in conventional computers. Two strategies are suggested for its implementation as a software module in the paper. One is to integrate it with the supervisory system in a substation control room operating in a LAN environment. In this configuration, the parallel transformers can be controlled locally. The other is to integrate it into the SCADA (Supervisory Control and Data Acquisition) system, which allows the transformers to be monitored and controlled remotely over a wide area of power-network. The implementation of µC based tap changer control needs interfacing between the power system and the control circuitry. µC s may need to interact with people for the purpose of configuration, alarm reporting or everyday control.
A human-machine interface (HMI) is employed for this purpose. An HMI is usually linked to the SCADA system’s databases and software programs, to provide trending, diagnostic data, and management information such as scheduled maintenance procedures, logistic information, detailed schematics for a particular sensor or machine, and expert-system troubleshooting guides.
OBJECTIVES: The original system can afford the following features:
- Complete information about the plant (circuit breakers status, source of feeding, and level of the consumed power).
- Information about the operating values of the voltage, operating values of the transformers, operating values of the medium voltage, load feeders, operating values of the generators. These values will assist in getting any action to return the plant to its normal operation by minimum costs.
- Information about the quality of the system (harmonics, current, voltages, power factors, flickers, etc.). These values will be very essential in case of future correction.
- Recorded information such case voltage spikes, reducing the voltage on the medium or current interruption.
- implementation of µC based tap changer control practically, using special purpose digital hardware as a built-in semiconductor chip or software simulation in conventional computers.

Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5.

Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.
