-Modelling and simulation software developed for analysing protecting relaying applications and relay design concepts in energy distribution is described inside the paper. The aim turned into to increase an open device that is simple to use and permits simple destiny expansions. Easy to use presumes that the software program should be appropriate for teaching functions that is accomplished by way of introducing new libraries of sign assets and relay elements evolved in the MATLAB / SIMULINK environment mixed with the SIMULINK / Sim Power Systems, the stated libraries enable an expansion of research aimed toward higher knowledge protective relay design strategies and processes and related programs in power gadget.Keywords -MATLAB, SIMULINK, Protective relay. I. INTRODUCTIONInside the MV networks in Croatia there are 3 methods of substation (transformer) neutral point grounding remedy: isolated, low-ohmic grounded and, from multiple years in the past, resonant grounded. MV distribution networks are especially radially operated. With an purpose to define the criteria for appropriate neutral treatment selection relying on the substation and MV network type, a top level view take a look at has been carried out currently. choice criteria in the have a look at considered: Technical functions of all 3 treatments regarding the earth-fault currents, over voltages and network operation based on literature, measuring, computer evaluation and operation experiences; Human safety necessities and rules (touch voltages), heath and voltage stresses and interferences with telecommunications strains; network importance (number and form of connected clients), length (period of galvanic related traces), kind (cable to overhead lines ratio, kind of poles and sorts of cable junctions and screens); community reliability (SAIFI and SAIDI); Earth systems necessities regarding earth fault currents and soil resistivity. Each criterion has been economically evaluated concerning capital and operation expenditure and then value-benefit analyses were made. The effects of those analyses are criteria for adequate neutral treatment choice regarding mentioned capabilities, requirements and policies. The examine also emphasized the need for guidelines protection concerning a brand new manner of operation and safety relay requirements as well as harmonization with eu norms. The want for implementation of recent safety methods and primary measuring gadget (contemporary and voltage transformers) coordination have additionally been taken into consideration and analysed. The evaluation done and the results carried out are described in this newsletter. In the scope of the observe, measurements of pre-fault and earth-fault currents and voltages were conducted in 10 kV and 20 kV distribution networks provided from HV/MV substations. Earth-faults have been executed with different fault resistances and types in addition to by way of using distinct neutral factor grounding strategies: isolated, low-ohmic resistive and resonant.

“…Much effort was invested during the last three decades to develop accurate and sophisticated models to represent the behaviour of the power system components. While off-line power system transients simulators such as the EMTP [6], EMTDC [7] and Power System Blockset [8], successfully cope with the requirements of system planning and transient studies areas, the off-line simulation environment exhibits great limitations when sensitive equipment is required to be tested in a closed loop with the modelled power system or when real-time decision is a must. This called for the development of a new breed of power systems simulators which could cope with these limitations.…”

The present work introduces a methodology to obtain a discrete time state space representation of an electrical network using the nodal [G] matrix of the Electromagnetic Transients Program (EMTP) solution. This is the first time the connection between the EMTP nodal analysis solution and a corresponding state-space formulation is presented. Compared to conventional state space solutions, the nodal EMTP solution is computationally much more efficient. Compared to the phasor solutions used in transient stability analysis, the proposed approach captures a much wider range of eigenvalues and system operating states. A fundamental advantage of extracting the system eigenvalues directly from the EMTP solution is the ability of the EMTP to follow the characteristics of nonlinearities. The system's trajectory can be accurately traced and the calculated eigenvalues and eigenvectors correctly represent the system's instantaneous dynamics. In addition, the algorithm can be used as a tool to identify network partitioning subsystems suitable for real-time hybrid power system simulator environments, including the implementation of multi-time scale solutions. The proposed technique can be implemented as an extension to any EMTPbased simulator. Within our UBC research group, it is aimed at extending the capabilities of our real-time PC-cluster Object Virtual Network Integrator (OVNI) simulator.

“…The nonlinearities in transformer core, saturation of transformer are the main causes of harmonics in inrush currents [10]- [12]. The application of Power System Blockset (PSB) in MATLAB/Simulink based simulation tool is discussed and various examples have been analyzed [13]. The Artificial Neural Networks are used as best forecasting techniques in engineering application; these are used in power system restoration problem and applied on 162 bus transmission for analysis [14].…”

In this research work Radial Basis Function (RBF) Neural Network (NN) and Regression models are used to estimate Temporary over Voltages (TOVs) that are occurred during the reenergization of lightly loaded transformer. Assessment of the TOVs are carried out in order to control the high peak voltage up to a safe operating point to ensure the safety of the power system equipments. The proposed approaches are applied to the standard IEEE 30 bus test system to evaluate its efficacy. The statistical approach is applied to examine the robustness of the forecasting results. Results show that the methods conveyed in this research are better and could be helpful for power system restoration planning.
