This thesis is to study the distribution system loss by applying the outage management system (OMS). To enhance the efficiency of loss analysis, the distribution system network has been obtained by retrieving the component information from OMS database. The topology process and node reduction have also been applied to identify the network configuration and to prepare the input data for load flow analysis. The load survey study is used to derive the typical load patterns of various customer classes. With the monthly energy consumption of customers served by each transformer, which has been retrieved from the customer information system (CIS), the hourly loading of each distribution transformer is then derived. By executing the three phase load flow analysis for different types of distribution feeders, the power loss of distribution feeders has been obtained, which will be used to evaluate the operation efficiency of whole distribution system.
To demonstrate the effectiveness of proposed methodology to solve distribution system loss, three practical distribution feeders in Taipei City District of Taipower are selected for computer simulation. With many transformers to serve voluminous low tension residential and commercial customers and high tension commercial and official customers in Taipei, the transformer core loss and high tension line loss contribute most of the distribution feeder loss. According to distribution feeder loss analysis, the transformer copper loss and low tension line loss are varied with the customer loading. With the distribution system loss model derived in this thesis, the distribution system loss can be estimated in a very efficient manner, which can provide utility an effective tool to analyze the power loss of whole distribution system and each individual feeder for assessment of system operation efficiency.
