This paper presents an efficient strategy for transformer planning to reduce the system losses by means of transformer rearrangement. The customer connected to the distribution transformer are first investigated by the field survey, and the loads of the various customers are collected from the customer information system (CIS) and distribution database system (DAS) to derive their load patterns. The objective function is to minimize the total line loss in the 24 intervals. An improved bacterial foraging algorithm (IBFO) is proposed herein to find the optimal phase combination of distribution transformers to minimize the total line loss by considering operating constraints. A three-phase load flow program with Eeuivalent current injection (ECT) is used to solve the total line loss and system unbalance factor on a Taipower distribution system. The results can help operators not only perform the proper installation phase selection of distribution transformers, but also reduce the system losses, decrease the system unbalance factor, and improve the voltage profiles of the buses.

Transient analysis for large rising mains is performed to protect them from worst effects of water hammer. It requires costly surge analysis software for analysing system for surge & sizing surge protection devices. If software is not available, engineers requires, selection charts or formulae pertaining to quick sizing of surge protection device for given pumping main. If size of surge protection device is known suitable cost shall be considered in budgetary estimates. Surge anticipating valve is a cost effective, compact & reliable surge protection device used in pumping mains. It is installed on delivery manifold of the pump. There are no design guidelines or selection charts available by valve manufacturers for selection of surge anticipating valves. Hence in this paper, charts are prepared to estimate amount of surge & size of surge anticipating valve using KYPIPE TranSurge software after numerous analysis of pumping mains for various combinations of flows, diameters, elevations and lengths. In the end, software results are validated by comparing it with results obtained by experiment.

The Gaz de France network is a combination transmission and distribution system with numerous sources, storage areas, and customers and with numerous interconnections between main lines. This nature of the network and its associated operating techniques require that special attention be given to the selection of compression equipment. This paper discusses the factors considered in this selection process and describes the method used to evaluate various equipment proposals.
