To test such protection systems properly, a distributed end-to-end test with synchronized injection is required. The first challenge for such a test is the correct calculation of the voltages and currents to inject at both (or even multiple) ends. Therefore, a simulation of the fault scenario based on the power system network, is needed which can deliver all of the required values. For the execution of an actual fault scenario (shot), a single software application which controls all test devices on both (or multiple) ends from a single PC, is much more convenient and productive than separate software applications, which have to be operated manually for synchronized injection. Controlling a remote test device is now possible using an existing Internet connection at each end of the test.","PeriodicalId":330524,"journal":{"name":"2013 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115771265","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}

In this paper, with PSCAD/EMTDC simulation platform, a doubly fed HVDC model is built by adopting the CIGRE HVDC benchmark system. And the demand rule for dynamic reactive power in HVDC transmission system is studied by using the control variable method, considering various control modes and stiffness of electric coupling between HVDC inverters. Some preliminary relation curves between reactive power demand and different factors are outlined. The simulation results show that under constant voltage control inverter would absorb much reactive power and a critical coupling distance exists which would distinguish the two trends of reactive power in inverter station.","PeriodicalId":330524,"journal":{"name":"2013 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124275711","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}

The prediction error of wind power generation capacity is large, so it's difficult to quantify its impact on AGC adjustment capacity and incorporate wind power maximally. To solve the problem, an active power real-time control method for wind farms considering AGC adjustment capability limits is proposed in this paper. Base on the strategy, the net-load fluctuation of next period is estimated according to the newest wind power and load predication information, the reference power of wind farm can be determined combined with the adjustment capacity of AGC. At the same time, in order to improve the value of wind power, an additional frequency control loop is design for the down-regulated wind farms. The simulation result demonstrates the feasibility of the proposed strategy.","PeriodicalId":330524,"journal":{"name":"2013 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122594677","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}

As a value that cannot be measured directly, the SOC is usually indicated by a method based on the characteristics of the battery with the voltage, current and temperature. In this paper, an extended Kalman filter (EKF) algorithm has been introduced to estimate SOC. A circuit model of a LiFePO4/C battery for EKF algorithm was proposed, so did the means for identification of model parameters. The parameters are categorized into two classes, the charge ones and the discharge ones. The SOC estimation method is validated by experiment data collected by battery test system (BTS). The result shows that the circuit model is suited to the battery and EKF methods, especially the one with parameters changing with current direction, can estimate SOC accurately.","PeriodicalId":330524,"journal":{"name":"2013 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"212 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114150758","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}

To cope with these challenges, many control methods for Power Factor Correction (PFC) have actively been proposed. This paper explains the design of a power factor improvement circuit using PIC (Programmable Interface Controller) chip with reduced parts count to achieve desired efficiency and low cost. This involves measuring the power factor value from the load and uses an algorithm to determine and trigger switching capacitors in order to compensate for excessive reactive components to increase power factor value. MicroC compiler has been used to build a C language code and the algorithm has been implemented in Proteus ISIS simulator which gives the desired results of power factor improvement fairly close to unity to cut down excessive penalty imposed on customers with heavy industrial loads having poor power factor.","PeriodicalId":330524,"journal":{"name":"2013 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122130470","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}
