The potential is for an energy revolution as profound as the impact fiber optics has had on communications. The fiber optic \"information superhighway\" was constructed by replacing copper wires with a higher capacity alternative. Superconductivity provides an \"energy superhighway\" that greatly improves efficiency and capacity. The economic and energy impacts are predicted to be huge. Many challenges had to be addressed in order that superconductivity could play this important role in the US electric power system. The US Department of Energy has worked in partnership with industry to solve the difficult challenge of manufacturing electrical wire from the ceramic high temperature superconducting (HTS) materials, while in parallel, creating designs of super efficient power devices that use these wires. The benefits will be substantial: HTS wires that are a resistance-free alternative to conventional wires while carrying 100 times the amount of electricity; and electrical equipment that is environmentally benign, with half the energy losses and half the size of conventional alternatives.","PeriodicalId":253534,"journal":{"name":"2001 IEEE Power Engineering Society Winter Meeting.

Economic and performance indices are always conflicting factors in the design of the practical devices and an acceptable design of practical device must be based on a reasonable compromise between these two factors. Although an overwhelming number of studies have been conducted on the UPFC and its application, the study at the components level is limited, especially regarding the selection of parameters of UPFC devices. Using the analysis of transient characteristics of UPFC installed in a power system, this paper attempts to identify the effects of the size of DC capacitor and equivalent line inductance. The relationship between the transient stability of the power system and these parameters is studied at the components-level simulation. The findings of this study can be useful in the determination of UPFC parameters for the purpose of improving transient stability, and highlight some of the practical considerations in UPFC implementation.","PeriodicalId":253534,"journal":{"name":"2001 IEEE Power Engineering Society Winter Meeting.

Ancillary services-reactive and voltage control 辅助服务——无功和电压控制

These six services constitute system control, reactive supply and voltage control, regulation, operating spinning reserve, operating supplemental reserve and the energy imbalance. Besides these six services, there are additional six services for which the transmission providers are not responsible. These six services constitute load following, backup supply, real power loss, dynamic scheduling, black-start capability and network stability. Despite the extensive preparations and planning by the ten electrical grid Security Councils, the combination of generation unavailability and limited transmission capability coupled with unanticipated circumstances such as extreme weather conditions could result in shortages of generation sources for reactive supply (VArs) and voltage control that could affect the security of the electric grid. This paper discusses mainly the reactive and voltage control portion of the ancillary services associated with the interconnected electric grid.","PeriodicalId":253534,"journal":{"name":"2001 IEEE Power Engineering Society Winter Meeting.

Active power filtering is performed by detecting the line current and voltage signals, generating a current equal-but-opposite to the distortion current using a power converter and injecting the compensating current into the power line. In such applications, it is desirable to combine high power and high switching frequency while minimizing the losses. This asks for special converter topologies and control techniques. In this paper, a multi-converter active power-line filter, based on current-source converter (CSC) modules, is proposed. The power rating and switching frequency of each CSC module is equal to those required for the filtering job divided by the number of modules. The control system utilizes two linear adaptive neurons (ADALINEs) to process the signals obtained from the line. The first ADALINE (the Current ADALINE) extracts the harmonic components of the distorted line current signal and the second ADALINE (the Voltage ADALINE) estimates the fundamental component of the line voltage signal. The outputs of both ADALINEs are used to construct the modulating signals of the filter modules. The proposed modular active filter offers the following advantage: (1) high efficiency due to low conduction and switching losses; (2) high reliability; and (3) high serviceability. The proposed active power-line filter treats the AC system on a per-phase basis, has fast response and adapts to the load variations. Theoretical expectations are verified by digital simulation using EMTDC simulation package.","PeriodicalId":253534,"journal":{"name":"2001 IEEE Power Engineering Society Winter Meeting.
