Pilot Wire Relay is a form differential relaying which protect longer lines through pilot wire, while pilot monitoring relay monitors the condition of pilot wire itself and gives transfer trip signal. However, Badak LNG has experienced two misoperations of auxiliary unit (TT) of pilot monitoring relay in 2009 and 2010. These misoperation was caused by activities of rack-in and rack-out vacuum circuit breaker at the same substation. Digital relay is the best solution to overcome this spurious trip problems because it is less sensitive to vibration and shock in addition to other several advantages such as: more compact in dimension, more complete protection, monitoring, metering and recording event.","PeriodicalId":334135,"journal":{"name":"2015 IEEE 5th International Conference on Power Engineering, Energy and Electrical Drives (POWERENG)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124120891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within the intention of a high torque and a high power factor both, the difference and the ratio of the direct- and quadrature inductance must be set to a maximum. In this paper an easy (semi-)analytic design method is used to determine these inductances for a reluctance machine with a standard induction machine stator and a multiple flux-barrier rotor. By varying the rotor and stator dimensions, such as the bore diameter and slot geometry, the effect on the difference and the ratio of the inductances and therefore on the output performance parameters is studied. For the analysis a simplified analytical model, such as a magnetic circuit model of the reluctance synchronous machine is created and solved iteratively. The RSM leakage inductances are determined by using the same analytical equations as used for induction motors. An optimum design for various objective functions like maximum torque, maximum torque per kVA and maximum torque per volume is found, by the means of the analytic model. As a result important conclusions are achieved, regarding the stator and rotor design, respectively.","PeriodicalId":334135,"journal":{"name":"2015 IEEE 5th International Conference on Power Engineering, Energy and Electrical Drives (POWERENG)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125038403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lightning protection zone is an essential parameter of lightning protection system, because it determines whether structure is protected against lightning strikes.

It can be done using renewable energy sources or by minimization of energy consumption. In industry case a lot of systems as CNC machines or industrial robots can regenerate energy. Regenerated energy is dissipated in breaking rheostats. To use regenerated energy usually use fast energy storage devices like flywheels or supercapacitors. In this paper are compared two topologies of interface converters for supercapacitor chargerging discharging in industrial DC grid with nonlinear load. These topologies are zeta-sepic and buck and boost. Both topologies are shown appropriate results. Buck and boost topology cheaper and produce less current ripples. Zeta-sepic produces larger current ripples, but better stabilizes grid voltage.","PeriodicalId":334135,"journal":{"name":"2015 IEEE 5th International Conference on Power Engineering, Energy and Electrical Drives (POWERENG)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134503239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Balance booster is a series RLC-circuit with a resonance frequency tuned to match converter switching frequency. Natural voltage balancing dynamics in the presence of balance booster placed in parallel to a converter load is aperiodic (non-oscillatory) similar to that of the same converter working with a pure resistive load. The equivalent load resistance is slightly increased that of the booster (roughly by up to 20-25%; natural voltage balancing rate is slowed down in the same proportion). Some basic Flying Capacitor Converter topologies are considered and approximate balancing time constant formulas are derived and confirmed by computer simulations.","PeriodicalId":334135,"journal":{"name":"2015 IEEE 5th International Conference on Power Engineering, Energy and Electrical Drives (POWERENG)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130197893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to increasing power transmission, the grid components experience a higher utilization rate. One essential issue of transmission grid planning is the necessity of the grid enforcement and the dimensioning of its components. Considering a similar level of grid security in case of failures, the level of grid security should not change after significant changes in grid structure and power flow. The (N-1) criterion can neither be used for comparison nor for assessing the severity of stochastic failures in grid assets. Therefore, probabilistic indices based on failure probabilities are introduced to complement the deterministic assessment of grid security. This paper presents a method for calculating indices based on a set of power flow situations with an appropriate simulation of failures.","PeriodicalId":334135,"journal":{"name":"2015 IEEE 5th International Conference on Power Engineering, Energy and Electrical Drives (POWERENG)","volume":"258 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122141754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
