Power generation control becomes progressively more complex as equipment dimensions and power output capabilities increase in the industry. Professional operators who understand plant systems need to be employed because they must make various operational decisions throughout the power plant. The modern power industry faces a primary challenge owing to the shortage of professional plant operators with proper skills and experience. The field of plant automation now focuses on artificial intelligence expert systems because these programs specifically replicate the operations of professional plant operators. This study conducts an analysis of numerous expert system implementations occurring in electric power plants. The evaluation demonstrates how expert system technology progressed through its combination with modern approaches that include fuzzy, neural network, machine vision, and data gathering systems. The use of expert systems to conduct plant fault diagnosis and maintenance enables a decreased workload for professionals as well as plant operators. The applications of expert systems include data processing as well as alarm reduction and schedule optimization and operator training and evaluation functions. The traditional rule-based methods combined with contemporary approaches which include neural networks, fuzzy logic, machine vision, databases and simulators have expanded expert systems' capacity to solve problems.

Designing proper characteristics for input filters of matrix converter systems ensures optimized input voltage distortion and decreased high harmonic components in main power supply currents. The input filter works at the power factor operation points which maintain unity. An input filter system allows for improving the power quality in the main supply current. An examination of power factor compensation through the design of an input filter takes place after presenting direct space vector modulation (SVM) switching patterns in this study. The proposed method proves its efficiency through simulated outcomes that utilize a permanent-magnet synchronous motor (PMSM) and an inductive load (RL).

This paper introduces genetic algorithm-based generalized optimization as a solution to determine optimal distributed generator locations within the 10-bus network with reactive power capabilities. The improvement of both voltage stability and profile depends greatly on reactive power management. The evolutionary genetic algorithm solved the necessary reactive power planning in this research by selecting the best individuals from parent to offspring generations based on biological metaphors. The genetic algorithm adopts chromosomes exclusively so it avoids needing any initial system knowledge to begin its search process while fulfilling the determined objective functions and relevant constraints. The stabilization of system voltage requires 325.7821 MVAR reactive power injected by the Static Var Compensator (SVC) as per this research analysis.

This paper examines an IEEE standard test system and uses MATLAB to test it using the Newton-Raphson method. Each bus's voltage magnitudes are analyzed, and FACTS like SVC and TCSC are added to the appropriate weak bus. The L-Index approach can be used to determine the best location for FACTS. When the L-index value approaches unity, it indicates that instability has been reached. The stability of the system is enhanced under fault and steady state situations from this instability point. By altering the Load Reactive Power at a certain bus, the system becomes disturbed.

Untreated industrial water discharges into existing waterbodies and onto land have degraded their quality and are now dangerous and catastrophic for aquatic and human life. Even treated industrial effluents have frequently been shown to be hazardous. Therefore, an attempt has been made in the project described below to test the treated industrial waste water and report the results to the pollution control board and the relevant industry. The water was tested using a thermistor, purity sensor, conductivity electrode (k=2), and pH electrode (PE03). ZigBee was then used to transmit the data from the aforementioned sensors to the pollution control board and industry control room.
