Accurate dynamic simulations are crucial for reliable and secure operation of a transmission system and the precision of power system stability analysis depends on the accuracy of the models used to represent system equipment. Therefore, the validation of power system dynamic models is critical for producing correct simulation results. Comparison of dynamic simulations with field measurements is necessary to validate the quality of a dynamic model. This paper presents the validation process for a Static VAr System (SVS) model with field measurements for a transmission system application. The SVS under consideration includes a STATCOM (a FACTS device) and coordinated mechanically switched shunt elements. This SVS was designed and installed for a renewable project for grid code compliance. The control parameters of this model were first estimated and then tuned based on the actual equipment control parameters to fit simulations to field measurements from the transmission system. Comparison of the model simulation results with the field measurements shows that the validated model generates responses very close to the field test results. The SVS model validation and submission to the transmission system operator is a requirement of the grid code. The validated SVS model has been successfully used for several transmission planning studies and is appropriate and accurate for these types of studies.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"154 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127574418","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}

When distribution networks are integrated with increasingly number of DGs, short-circuit current calculation becomes less convenient because the dimension of nodal admittance Y matrix expands a lot. This paper proposes a new model for short-circuit current calculation with a large amount DGs. Effects of those DGs on short-circuit current are modeled by a standard second-order linear ordinary homogeneous difference equation. With the proposed model, the nodal admittance Y matrix doesn't increase correspondingly when the amount of DGs increases. Thus, the proposed model saves a lot both in memory storage space and computing resource. Simulations are carried out in the IEEE distribution 33-bus system. Results demonstrate that the proposed model has equal accuracy as traditional method, and much higher efficiency in both memory storage and computing time cost.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130273183","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}

Wind turbines need to be operated as per specified power output vs wind speed characteristics of it. If the wind speed is between the cut-in wind speed and the rated wind speed, then the wind turbine needs to be operated constant Cp. If wind speed is between the rated speed and the cut-off wind speed, then the wind turbine needs to be operated for constant rated power. To extract rated power above rated wind speed a proper controller strategy is required. This work provides a simulation model for power regulation of a horizontal axis wind turbine system. In this work, power regulation using PID is implemented for the pitch control as well as the torque control along with the feed forward control strategies, when the wind speed is higher than the rated wind speed. This system consists of four models namely the wind profiles, energy extraction and torque generation model, gear system and the control system. The power regulation performance with proposed pitch controlling are presented for a selected wind profile.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116049380","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}
