Impact of increased distributed generation on fault levels and the network equipment

Attention towards the development of Distributed Generation (DG) is globally high. UK's concentration is to use sustainable and renewable sources to generate electricity thereby protecting the environment from getting polluted. In this paper, Distributed Generation concept is explored regarding the types, sizes, ratings, locations and benefits. It is very important to connect the developed distributed generator to the distribution network to satisfy the demand but without developing any faults and causing damage to the existing switchgear. Legal contracts that are required to be signed in order to connect the DG to the network and proper Protection Review to be followed in suppressing the faults are also mentioned. To study the impact of increased DG on fault levels, simulation approach is adopted. ETAP 7.1.0 is used to build a case study network and the results obtained are analyzed based on which critical comparison is made. The network comprises of three wind farms, each consisting of six wind turbines and a small hydroelectric plant. Various scenarios are considered and the results obtained are clearly analyzed. Protection is provided for the circuit and Star Device coordination study is performed. © JES 2014

A novel policy making proposition for EV charging infrastructure management at HEI's

This paper is based on real time EV charging infrastructure development that took place at Brunel University, which is located in west of London, UK. The aim of this paper is to establish the policy making process that has stages of an initial student-staff interest survey, records of the consultation process with EV owners, results of competitive benchmarking with other HEI's and the discussion on Type 2 Mode 3 charging stations which are 240V, 32A, 7kW, 50Hz compliant with IEC 62196 and ISO 14443 Mifare standards. The first time ever PAYG concept of POD Point Ltd is explained. Benefits of using PAYG concept for charging EV are mentioned. Various other factors that played major role were also considered as follows: deciding the tariff of the electricity used by the EV owners, charging cable compatibility with charging station, hours of operation, creation of new enforcement rules and recommendations to provide incentives that recognise and motivate EV community

A case of degenerated cervical fibroid polyp

Cervical fibroids are often solitary. It may be either interstitial, subserous, submucous or polypoidal. Cervical fibroid usually develops in the wall of the cervix, supravaginal portion. They can change the shape of the cervix or lengthen it, grow rapidly and obstruct the cervix. As fibroids enlarge they may outgrow their own blood supply leading to various types of degeneration. Cystic degeneration is observed in 4% is considered an extreme sequelae of oedema. However atypical appearances that follow degenerative changes can cause diagnostic confusion. Hence misdiagnosis of adenomyoma, hematometra, pyometra, uterine sarcoma and ovarian masses is common.

Combined power system planning and policy proposition for future electric vehicle charging infrastructure

This thesis was submitted for the award of Master of Philosophy and was awarded by Brunel University LondonIn order to achieve the UK Government’s legally bound framework of greenhouse gas reduction targets, the transport sector is undergoing drastic changes. The key action taken by the Department of Transport in addressing the issue was the introduction of Ultra-low emission vehicles (ULEV) concept. Office for Low Emission Vehicles (OLEV) was introduced to support early market for ULEV and development of efficient recharging network through Plugged-in Places programme. The massive deployment of EV charging stations across GB will have direct impact on GB power system as they require electricity supply for their operation. It is therefore deemed necessary to carry out investigations on the capacity of the network assets to handle this load and to develop policies to manage the future EV charging infrastructure efficiently. This thesis provides an overview of the EV technology introducing various technicalities behind EVs and the associated charging stations. The extended theory about interoperability between EVs and power networks is also presented. Investigation of an 11kV networked site and 66/11 kV networked area is performed to determine their potential in accommodating future EV charging infrastructure. A methodology has been proposed to carry out investigations in 11kV networked site. For analysis purpose both the real networks are modelled in detail using power system analysis software Electrical Transient Analyzer Programme (ETAP). Scottish and Southern Energy (SSE) and Northern Power Grid (NPG) are the owners of the distribution networks respectively. Collaboration with DNOs has taken place to collect the existing network data. Finally, a university based EV charging bays management policy has been proposed

Social Science – A springboard for life

Sociology’ and ‘Psychology’- I have shared a relationship of fascination with these two words from the time that I vaguely knew what they meant. It is quite absurd actually, the idea of studying society, people, their brains, emotions, reactions, (all of it/the whole lot!). Having studied subjects like English and Math for the first 16 years of my life, these topics seemed to be scattered, disorganized, and all-in-all impossible to look at through one fixed framework. How can our actions and feelings be explained by a set of theories and rules? True, they cannot. As I later found out, the social sciences are not monolithic, in that, they do not use one, single theory that everyone in the field agrees with and follows. They each carry their own view point, ideas, questions, and answers. Perhaps this is the reason that both sociology and Psychology contain many, many facets, and, for me, this multi-facetedness is one of the beauties of the social sciences

Profile of obstetric patients in intensive care unit -a retrospective study

Background: Obstetric patients form a particular subgroup of population to intensive care admission. Pregnancy specific problems like pre-eclampsia, postpartum haemorrhage or deterioration of pre-existent conditions can be sudden and life threatening, requiring immediate intensive management and monitoring. The main objective was to determine the pattern and outcome of obstetric admissions to intensive care unit. Methods: It was a retrospective study from June 2020 to June 2022. Obstetric patients admitted to intensive care unit were included in the study. Data were obtained from the patient’s case notes and records from the ICU and were entered into a predesigned proforma. Results: Maximum study subjects were between age group 21-25 years of age. Most of them were primigravida and admitted in the postpartum period. The most common indications for admission to ICU were preeclampsia with severe features followed by obstetric haemorrhage. The mortality rate was 18.8% and shock attributing to the main cause. Conclusions: Maternal and child health have become an important measure of human and social development. Early and prompt diagnosis and treatment of high-risk obstetric patients in intensive care unit can prevent and ameliorate serious maternal morbidity

Simulation analysis of wastes gasification technologies

Each year a significant growth in the amount of wastes generated is observed. Due to this fact technologies enabling utilization of wastes are needed. One of the ways to utilizes wastes is thermal conversion. Most widely used technology for thermal conversion is gasification that enables to produce syngas that can be either combusted or directed to further synthesis to produce methanol or liquid fuels. There are several commercially available technologies that enable to gasify wastes. The first part of this study is subjected to general description of waste gasification process. Furthermore the analysis and comparison of commercially available gasification technologies is presented, including their process arrangement, limits and capabilities. Second part of the study is dedicated to the development of thermodynamic model for waste gasification. The model includes three zones of gasification reactors: drying, gasification and eventually ash melting. Modified Gibbs minimization method is used to simulate gasification process. The model is capable of predicting final gas composition as a function of temperature or equivalence ratio. Calculations are performed for a specified average wastes composition and different equivalence ratios of air to discuss its influence on the performance of gasification (temperature of the process and gas composition). Finally the model enables to calculate total energy balance of the process as well as gasification and final gas temperature
