This paper presents a new method to estimate transformers pricing. The method is based on multilayer perceptron neural network (MPNN) with sigmoid transfer function. The back-propagation (BP) algorithm is used to adjust the parameters of MPNN. The required training data for MPNN are the obtained information from the transformers made by Iran-Transfo Company during last 4 years. A Multi-Layer Perceptron (MLP) neural network has been designed for 132/33KV transformers (which is classed as non-conventional in Iran). By finding suitable coefficients for weight of the copper, iron and transformer oil (that are MLP neural network outputs) and a constant coefficient that is related to manpower cost and other transformer components costs, the cost of transformer is estimated.","PeriodicalId":412111,"journal":{"name":"2010 International Conference on Future Power and Energy Engineering","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128559533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These are secondary circuit signals, fault recorder and PMU data. Fault recorder data contains the details of fault evolution, which can be used for diagnosis fault occurrence time, circuit breaker operation events. It is crucial for power grid diagnosis and intelligent alarm functions. However, the analysis and utility of fault record data for diagnosis purpose require the operator's participate and is time consuming. In this paper we design a two stages fault diagnosis mode for future development of IEC61850 and digital substation. Based on this, we propose a hybrid algorithm to analyze fault recorder data with abrupt change detection which can obtain major events during a fault, including fault occurrence, circuit breaker operation time. We use a simulated example to prove correctness and efficiency of our proposed algorithm.
