Proposed Model

Distribution networks are an essential part of all water supply systems. Distribution system costs within any water supply scheme may be equal to or greater than 60% of the entire cost of the project. The reliability of supply is much greater in the case of looped networks. The pipe networks have concentrated outflows or uniform outflow along the length of each pipe. In some pipes with variable discharge of a looped distribution network, water velocity could be reversed between its extremities. Thus, it is a water stall point denominated neutral point in which the discharge is null. In this paper a mathematical model for the determination of water stall point location in the pipes with distributed consumption is developed. This model has been implemented in a computer program for PC microsystems. Numerical example will be presented to demonstrate the accuracy and efficiency of the proposed model.

Mixed Distribution

The paper considers methods of configuration of arc-suppression coils in cable, air and mixed distribution networks of 6-35 kV. A special attention the authors have dedicated to influence of external factors (natural unbalance of network and interference) on configuration quality, as well as the maintenance of value of neutral point displacement voltage in acceptable limits. As a result, the authors have analysed the existing methods and suggested mew ones for elimination of influence of the specified factors.
