Aspects of the ratio of reactive to real powers as input to transmission network control

Swart, Sarica Meyer 05 June 2012 (has links)
D.Ing. / Transmission networks change continuously when new supply requests are made, network reinforcements are installed and equipment configuration changes. Therefore, network design, operation and control requirements change. To manage this, controllers are being developed to assist human network controllers who might not always be specialists in equipment operation and characteristics. A transmission network comprises multiple variables, some dependent on others. The resistive portion of a load (PLoad) and the total reactive power (Q) installed close to the load can be set in relation to each other. This relationship forms the basic concept of the QP ratio for a transmission network. This ratio is not standardly used as a variable in network operation or control. This thesis explores this new QP ratio in more depth for application in different networks. This concept is developed and investigated in detail and equations are derived from first principles. The usability of the QP ratio is described and calculations are done for existing networks. It is shown that each network has its own unique QP ratio that can be used as information for human operators or as part of a controller device. This information can assist in determining actions required to be taken by controllers and operators. This thesis investigates aspects related to the use of a QP ratio in transmission networks as far as system operation and network control is concerned. The information provided in this thesis could be developed further to assist in implementing of the QP ratio in transmission network control rooms or systems. This will contribute to the provision of more reliable, robust and controlled electrical networks.
