This three-step practical procedure can be used to develop a strategy for implementing reliability improvement programs on a particular distribution system, so that given cost and reliability performance targets can be addressed.","PeriodicalId":182269,"journal":{"name":"2001 IEEE/PES Transmission and Distribution Conference and Exposition.

Many installations in the USA are being refurbished, since the existing installations can no longer cope with the increased short circuit level. The installed gaps are mostly of the self triggering types and the available MOV-energy is not sufficient to handle the short circuit current. Even the capacitors have to be replaced, since they contain environmentally harsh PCB. In some other cases, there is a need to improve the system dynamic performance and avoid subsynchronous oscillations due to their damaging effects on turbogenerators. TCSC (thyristor controlled series capacitors) schemes are being used more often in the form of FACTS-technology to improve system dynamics. The platform equipment is also undergoing a transition, since the utilities prefer maintenance free equipment and less electronics at the high voltage level. There is also a strong desire to keep the banks switched on (not bypassed; improved life time of bypass breakers through avoidance of unnecessary close-open duty cycle) even for line currents up to zero. All these requirements have led to a rethinking regarding the control and protection practices of series capacitor installations. This paper describes innovative solutions implemented in some of the installations and the experience gained during system operation.","PeriodicalId":182269,"journal":{"name":"2001 IEEE/PES Transmission and Distribution Conference and Exposition.

The first step in the analytical approach is to develop a load flow model for contingency analysis. This allows the identification of system steady-state low voltages or voltage collapses following contingencies. The second step is to apply an optimization algorithm/model to determine the reactive margin, or the amount and location of reactive compensation required to eliminate the low voltages or voltage collapses. P-V or Q-V curves are generated for comparison in this step. The final step is to verify the voltage stability response to the contingencies via time-domain simulation, including the impact of different load models.","PeriodicalId":182269,"journal":{"name":"2001 IEEE/PES Transmission and Distribution Conference and Exposition.

The instrument can be installed outside the 'hot zone' around the wires. It measures the current in each individual wire in real time and can feed this information to a range of backend applications. A full description of the currents in an overhead line is embedded in the magnetic fields in the vicinity of the line. We can decode this information by measuring the magnetic fields and wire geometry at a position near the line. Initial applications include load recording and power quality monitoring. Stand-alone instruments can link to automation systems over communication links. This technology can help leverage the powerful communications and digital processing technologies now available by providing a current interface for high voltage networks.","PeriodicalId":182269,"journal":{"name":"2001 IEEE/PES Transmission and Distribution Conference and Exposition.

Paper degradation after aging is determined using paper tensile strength and degree of polymerization measurements. The paper in natural ester aged at slower rates than did paper in conventional transformer oil, taking 5-8 times longer to reach end-of-life. Results obtained for mineral oil samples are similar to predictions based on IEEE transformer loading guide calculations.
