    Summary form only given. Utilities are facing higher levels of uncertainty in their planning process than ever before. The old days of integrated resource planning, in which generation and transmission plans were coordinated, are largely gone. Long range transmission planning must now include consideration of a wide range of possible generation additions and retirements, which are outside of the c... View full abstract»

    Integrated planning has disappeared with the separation of generation and transmission entities. As a result, generation location is not necessarily taking place in locations that will provide for the most efficient development of both generation and transmission. Further, more generation is being considered for developed in certain markets than will be able to be accommodated. The transmission pl... View full abstract»

    The prospect of merchant transmission as an enterprise unto itself poses several interesting business issues. Merchant transmission (as opposed to rate-regulated, tariff based revenue transmission) is a very different business proposition and poses its own set of issues for management, regulators and investors. Although these issues have some overlap and resemblance to the issues involved in more ... View full abstract»

    The growth of the merchant generation has largely de-coupled generation investment decisions from transmission investment decisions. The introduction of economic incentives through the creation of deregulated, competitive wholesale markets with clear market rules has led to a tremendous boom in merchant power generation plans in the past several years. Taking a lead from merchant generation busine... View full abstract»

    Many believe that the single most important factor in the failure of the transmission system to promote and facilitate the restructuring of electric power industry is the breakdown of both traditional transmission planning processes and the emerging market-based incentives for identifying and realizing the needed transmission expansions. These difficulties have been exacerbated by uncertainty abou... View full abstract»

    Merchant transmission, which may be built by incumbent utilities or new entrants to a power market, will be built to allow lower cost generation access to customers in areas where the competing generation is higher cost. Without new transmission projects, the price discontinuity between areas results in congestion as customers in higher priced regions attempt to buy supply from lower cost regions....

  • Impact of current transformer saturation on overcurrent protection operation

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (964 KB) | HTML iconHTML

    If current transformer (CT) characteristics are not properly selected for fault conditions, saturation will occur which can affect protection device operation. In some applications even if CTs are properly sized, it is necessary to locate protection devices far from the CTs. In these cases, the wire resistance, which adds to the CT burden, causes CT saturation at smaller currents than when located... View full abstract»

    If current transformer (CT) characteristics are not properly selected for fault conditions, saturation will occur and relays can have delayed response or even fail to trip. To verify that CT saturation will not cause mis-coordination with other protection devices a study needs to be performed, which requires CT modeling. This paper compares different CT computer modeling techniques. Models of a 12... View full abstract»

    The physical interpretation of wavelet transform is presented in this paper by comparing its band pass filter properties with that of short time Fourier transform. The fault signal on a practical 500 kV power system as generated by EMTP is analyzed with Morlet wavelets. It is shown that wavelets with automatically adjusted time windows can be used to capture and analyze fault-induced transients fr... View full abstract»

    Computer modeling of relays helps engineers understand how protection systems behave during faults and other disturbances. Simulators can assess the reliability of a protection system, determine the effect of correct and incorrect operation on a power network and if necessary help a relay manufacturer investigate new design ideas. The PSCAD/EMTDC transient simulator was used to model the effect of... View full abstract»

    Summary form only given as follows. In long line applications that involve tripping the faulted phase in case of LG faults, the single-pole autoreclosure is extensively used. Traditional phase selectors can suffer some deficiencies in their performance due to varying system and fault conditions.

    The paper presents an approach to locate a fault in a transmission network based on waveform matching. Matching during-fault recorded phasor with the during fault simulated phasor is used to determine the fault location. The search process to find the best waveform match is actually an optimization problem. The genetic algorithm (GA) is introduced to find the optimal solution. The proposed approac...

    This paper describes how the fault generated travelling waves detected in the current signals at a single location on a distribution feeder can be used for fault section identification and location. The method identifies the fault section and the probable location of the fault by comparing the relative distance of each "peak" in the high frequency current signals to the known reflection points in ...

    Accuracy and reliability are the most important indexes to evaluate a transmission line fault location algorithm. Researchers have been focusing their efforts on the accuracy of the fault location algorithm, and the reliability of the algorithm seems to have been ignored before. In fact, if a fault location algorithm is exact but unreliable, it is of no use! It is necessary to give equal attention... View full abstract»
