EPR-insulated cables for distribution power network are not commonly used in Australia. This is due to the higher DDF of common EPR cables when compared with XLPE that contributes to the power loss and economics in transmitting electricity. This led to the development of EPR called TR-EPR with significantly lower DDF and uses silane curing process to address concerns about cost-effectiveness. The thermal behavior of low DDF silane cure TR-EPR is investigated for 30 months of exposure to the maximum operating temperature of material. The physical changes in the samples throughout the long-term aging are examined to create an opportunity to model the expected life cycle of TR-EPR cable under thermal stress. The cross-linking characteristics of TR-EPR cable are also examined by ambient curing that simulates the storage condition for unused cable and by cable heating process that simulates the condition when the cable is energized. The results are tabulated for a better understanding of the time for the material to cross-link at various conditions. The improved partial discharge values after cross-linking are also presented.

Currently, the use of underground electric cables is a regular feature of present-day power transmission and distribution schemes. Issues related to economical limitations and the lack of adequate space led to the need for cables with an elevated current carrying capacity (ampacity). In order to achieve this objective, public services around the globe are focusing not only on better designs, but also on improving the level of precision in the context of cable parameter values. Precise parameter values are essential for ensuring that the replicated outcomes correspond sufficiently close to actual circumstances. While the conventional approach to ampacity calculation is through the IEC-60287 procedure, the numerical route is considered more specific and flexible. This endeavour harnesses the finite element method to conceive an innovative process for calculating the thermal field and ampacity of a cable. This process involves the crafting of a temperature field distribution model for scrutinizing temperature distribution in the region of an electric cable, and the deployment of the linear interpolation procedure for computing its ampacity. Subsequent to its formation, the model was put into operation on the underground cable 33KV XLPE.

The developments in power quality are fast and difficult to predict. The majority of power quality issues experienced by industrial customers can be attributed to momentary interruptions, voltage sags or swells, transients, harmonic distortion, electrical noise, and flickering lights, among others. A new device may be invented tomorrow solving power quality problems. The FACTS devices could provide fast control of active and reactive power through a transmission line. The unified power-flow controller (UPFC) is a member of the FACTS family with very attractive features. This device can independently control many parameters, so it is the combination of the properties of a static synchronous compensator (STATCOM) and static synchronous series compensator (SSSC).The performance of AC Transmission system with Unified power flow controller under various power quality problems analysis described. The proposed system is formulated and research work is done by wavelet multi resolution analysis using Bior1.5 mother wavelet with MATLAB/SIMULINK software. It is observed that the effectiveness of AC power transmission through Unified power flow controller under power quality problems of sag, swell, transient, temporary faults and capacitive switching.

The dynamic model construction of transmission network components that include generator buses, load buses and power branches, within MATLAB-Simulink environment is presented. The degree of frequency deviation of buses when the power of motor loads and static loads vary, is studied. Furthermore, the influence of motor loads with different inertia constants are considered in the control technique of load frequency using a PID controller. The results show that the frequency oscillation of the dynamic load is greater than the frequency oscillation of static load. Also the speed of frequency control of the dynamic load is greater than the speed of the frequency control of the static load and the inertia constants of the dynamic load has significant influence on the frequency control characteristics.

This manuscript reports the monitored performance results of roof top solar photovoltaic (PV) power plants in different parts of Tamilnadu, India. In this work, PV plants of capacities 84 kWp and 18 kWp located at Tirunelveli and Ranipet respectively in Tamilnadu are considered. During an eight month period, of September 2014 to April 2015, these plants had generated 43.99 MWh and 15.55 MWh units of electricity respectively. The average electricity production per day for the considered period of these plants is 181.74 kWh and 62.81 kWh respectively. The performance ratio (PR) of these plants PV1 and PV2 is found to be 0.52 and 0.86 respectively. The characteristics of poly crystalline PV modules and the performance of employed photovoltaic inverters are also analyzed.It is observed that external conditions like climate and bad weather significantly reduces the PV system output, whereas it reduces marginally due to inverter failure as observed from the values of energy yield and performance ratio of these plants. Online monitoring of PV plant with DC/AC line and phase voltages and current waveforms observed for the given day are also presented.

This paper proposes a cascaded H-Bridge Multilevel inverter for induction motor drives (CHMLI). Multi-level Inverter (MLI) has several advantages over conventional inverter such as lower total harmonic distortion (THD), low switching loss, good power quality, high output voltage. The main feature of multilevel inverter is that it uses many small dc sources to supply various output levels. The H-bridge cascaded MLI is chosen in this paper because it requires least number of components for same voltage level. The H-bridge cascaded MLI with five levels is designed. The simple multi carrier SPWM techniques namely phase disposition (PD) or phase opposition disposition (POD) is usually used to generate pulses for the MLI.In this paper, a new topology of Multi Carrier PWM techniques known as Hybrid Trapezoidal Carrier PWM Technique (HTrap) is used to control switching of multilevel inverters with a squirrel cage induction motor drive.The H-bridge cascaded MLI with five levels using HTrap modulation technique is simulated and synthesized for induction motor drives. The performance of designed CHMLI fed induction motor drives is investigated extensively for various operating conditions through SIMPLORER simulation. The performance of CHMLI with HTrap modulation technique is also compared with other conventional multicarrier techniques in terms of inverter performance parameters (total harmonic distortion, THD, harmonic factor, HF and crest factor, KF). The promising and interesting results obtained are comprehensively presented.The five-level multilevel inverters with HTrap showed to have the lowest THD, HF and KF when filters are not used as compared to other Multicarrier PWM Techniques. If the cost is important the two-level inverter should be used, since it has the lowest cost between all of the inverter topologies. If the power losses are important, the five-level is the best choice since it has the lowest power losses than the two level inverter. Selection of a multilevel inverter is a tradeoff between cost, complexity, losses and THD. The most important part is to decide which one is more important.

The main focus on this paper deals with a current control technique for the inverter using a PV system for grid connected topology. The work of this paper is to evolve the PV model by tracking maximum power point using Incremental conductance algorithm using a single phase transformer less synchronous reference frame control method for cascaded H Bridge Multilevel Inverter via boost converter system connected to 230V single phase grid. A Phase shifted pulse width modulation technique is also projected in order to afford the pulse for voltage source inverter. The mathematical expressions for the control design for the single phase system is expressed in this paper.The analysis of the control is adopted using PI control method and is executed in synchronous rotating d-q reference frame in order to carry out the response of the best output voltage for the grid connected single phase PV system. The d-q technique is applicable only for the three phase system due to the minimum requirement of two independent phases. Hence one quadrature phase inverter is added additionally in the control method. The simulation is done using MATLAB/SIMULINK.
