The use of automation and energy efficient equipment with electronic control would greatly improve industrial production.  These new devices are more sensitive to supply voltage deviation and the characteristics of the power system that was previously ignored are now very important. Hence the benefits of distribution automation have been widely acknowledged in recent years. This paper proposes an efficient load flow solution technique extended to find optimum location for reactive power compensation and network reconfiguration for planning and day-to-day operation of distribution networks.  This is required as a part of the distribution automation system (DAS) for taking various control and operation decisions.  The method exploits the radial nature of the network and uses forward and backward propagation technique to calculate branch currents and node voltages.  The proposed method has been tested to analyze several practical distribution networks of various voltage levels and also having high R/X ratio.

Compensation Rate

A method based on modeling approach that from points to face and boundary conditioned parameter is put forward in this paper. Starting from the Point Model with statistical characteristics, the characteristic parameters which influence the configuration rate of reactive power compensation (RPC) are adopted as boundary conditions. Expanding from Point Model to Analysis Model, different features of actual 20kV cable distribution feeders can be covered. Then, with the optimization research on RPC of urban cable lines in 20 kV distribution networks, the recommended range of RPC rate in different transformers is worked out, which can be extended to the application of 20 kV urban distribution network. The simulation shows that the proposed method can optimize the reactive power configuration in 20 kV distribution networks without the complicated computation of optimal reactive power planning.
