Challenges in Protection Relay Testing for Tomorrow’s Power Grid
Very many challenges related to protection relay testing are met today in the field and in the research industry.
There are often new and more complex applications such as wind turbines, very fast switching power electronics, photovoltaic cells and the battery and electric vehicle technologies. This implies among other things new converter topologies and smart grid considerations. These systems cannot be protected the same way as what was already being done, so this increases the complexity of the algorithms used.
Real-time simulation is a novel approach to design and test protection relay algorithms.
How to Create and Implement Protective Relay Test Plans
The document provides guidance on creating and implementing protective relay test plans. It discusses reviewing relay application drawings and settings, establishing communication with the relay, connecting the relay set for testing, creating a test plan, performing element and logic testing, and generating a final report. Key steps include verifying CT and PT ratios and connections, labeling test switches, and testing individual elements and the overall logic/operation of the relay.

BUS BAR PROTECTION PPT BY:-R.K.PANDIT
Bus bars are the nerve center of a power system where various circuits are connected. Differential protection is suitable for bus bars since terminals are near each other, allowing comparison of current entering and leaving via CTs. Any difference signals an internal fault and causes the relay coil to trip circuit breakers on both sides, isolating the bus. CT ratios for bus differential schemes equal the maximum feeder current divided by 1 or 5 amps. External faults may cause maloperation if a CT saturates, but a stabilizing resistance can restrain the relay. Dot convention defines the direction of current flow in CT secondaries. Only class PS CTs should be used to avoid undesired difference currents. Differential protection is important to protect bus bars

Case Study - How we saved a Process Plant from break-down
During routine maintenance and testing of switchgears at a cement plant, a CT on a critical TIE feeder was found to have a highly resistive secondary winding. Further inspection revealed that the secondary winding was cracked and barely attached. Advanced CT testing equipment was able to detect this issue, even though the CT had been functioning normally. If undetected, the cracked secondary winding likely would have led to a complete failure that could have caused an outage across the entire plant. Routine diagnostic testing of equipment like CTs and PTs is important for detecting potential issues before they cause operational problems or equipment breakdowns.

An earth fault was tripping a plant's LT PCC incomer feeder whenever the load increased beyond a certain limit. The fault was derived earth protection that relied on phase CTs. Testing found one phase CT had a 50% ratio error and 1574 minute phase angle error, unbalancing currents. Replacing the faulty CT solved the issue and allowed earth protection to be re-enabled. Advanced CT testing equipment found the error that routine testing had missed, highlighting the value of continuous technology upgrades.

The document describes a case study of a process plant where three motors were burnt in 9-10 months due to a faulty protection scheme design. The protection scheme used common current transformers (CTs) and relays for motors and capacitor banks, which caused issues. Specifically, the relay would not properly sense faults on the motors as the current drawn would be lower when capacitors were connected, and it would take engineers longer to identify fault locations. The solution was to implement separate protection for motors and capacitor banks with manipulated motor protection relay settings until the scheme was modified. This would prevent future motor failures and downtime.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
