Stability and safety margins of a weak station within a multiterminal HVDC system
Interaction with inverters at AC power systems with low relative short-circuit capacity have been summarized recently. In a multiterminal HVDC system an inverter station which is weak in rated power, in the short-circuit-ratio, or both, pos...
Simulator study on line fault clearing by DC circuit breakers in a meshed MTDC system
HVDC multiterminal power systems, here referred to as MTDC systems, request increasing interest after the first schemes of this kind are in operation or under commissioning, respectively. A variety of system configurations can be defined wh...
Interconnection of a large hydro power plant via HVDC and AC links with two remote grids
The authors describe the analysis of electromechanical transients in a large hydroelectric power plant interconnected via HVDC and AC links with two separate power systems. The investigation shows the dynamic behaviour of the total intercon...
Review of the design of the James Bay-Boston DC system
The design of the James Bay-Boston 450 kV system is a reflection of the planning and operating requirements that led to its adoption and which in turn led to constraints in its implementation. The authors take a second look at this multiter...
The Hawaii geothermal/interisland transmission project
In May 1989, Hawaiian Electric Company, the electric utility serving Honolulu and the island of Oahu, issued a request for proposal for the purchase of electricity produced from geothermal resources on the island of Hawaii and transmitted b...
The Amazon transmission technological challenge
The Brazilian power system consists of two interconnected systems. As power resources near the country's major load centers become exhausted, the transmission system will enlarge its interconnection as part of the long range expansion strat...
Economic efficiency, independent power producers and wheeling
Traditionally, electric utilities have sought to decrease the cost of production by such means as merit order running of machines, by improving equipment efficiency, by fuel mix, by interconnection and exchange of cheap energy, and by unit ...
Wheeling and transmission system service policy in North America
The authors provide a review and discussion of the status of wheeling in the USA and Canada; the pros and cons of the new policies that are evolving and under consideration for wheeling and transmission access; specific case examples of som...
The single European energy market: the electricity supply sector
The completion of the internal market in the Community by the end of 1992 has become a key objective and the focal point of the revival of the European Community. Within this overall objective, the development of the single European energy ...
The structure and operation of the privatised UK electricity supply industry
The National Grid Company has just over a years experience in running the England and Wales Grid System as a plc in a market led environment. The industry has been restructured for privatisation with NGC Holdings, owner of NGC plc, being jo...
