Planning of the Gulf States interconnection
The authors deal with the planning studies that were carried out to determine the feasibility and nature of an interconnection of the Gulf States. The interconnection project is foreseen to be developed in three phases. The authors give a d...
Power system studies and modelling for the Kayenta 230 kV substation advanced series compensation
The Western Area Power Administration (WAPA) requires additional power flow capability between Shiprock substation in New Mexico and Glen Canyon power plant in Arizona. To increase power flow capability, it was decided to series compensate ...
AC/DC system strength as indicated by short circuit ratios
Although from the very early HVDC schemes the designer had to contend with effects of 'weak' AC systems, a good understanding of the interactions between AC and DC systems has been established only over the last few years. The 'strength' of...
A unified flow control concept for flexible AC transmission systems
The control of an AC power system in real time is involved because power flow is a function of the transmission line impedance, the magnitude of the sending and receiving end voltages, and the phase angle between these voltages. It has been...
FACTS options permit the utilization of the full thermal capacity of AC transmission
In the United States, EPRI is supporting the development of FACTA (flexible AC transmission systems) technologies, which enable the control of power flow on AC transmission lines and utilize the existing transmission facilities all the way ...
FACTS-flexible AC transmission system
For economic reasons most if not all of the worlds electric power supply are widely interconnected, involving interconnections inside utilities own territories which extend to inter-utility interconnections and then to inter-regionals. The ...
Enhancement of transient stability on AC transmission by means of controlled series and parallel compensation
Long distance AC transmission is often subject to stability problems which limit the transmission capability. To increase the transmission capability power system stabilizers (PSS) and series compensation have been used for decades. For dam...
Digital simulation of HVDC transmission and its correlation to simulator studies
In order to investigate the behaviour of HVDC transmission in a power system, suitable simulation models are required. A detailed commutation model with simulation of the thyristor bridges, while very precise, requires considerable time for...
Modelling of VSC Converters in the Rotating dq Frame for DC Fault
As the future DC grids will involve numerous converter systems, the accuracy and speed of their modeling becomes of high importance. The modelling in a rotating dq frame is able to transform the quantities from ac variables to dc variables ...
Impact of renewable generation on commutation failures in multiinfeed HVDC systems: a real case study
HVDC technology is a key driver for the integration of renewable energy sources (RES) in large transmission systems. However, the displacement of conventional thermoelectric power plants due to RES development can hinder safe operation of L...
