In power transmission and distribution systems power electronics does not compare in efficiency and cost and only provides support where conventional technology is not incapable of performing the task. With the promise of Silicon Carbide (SiC) based IGBTs rated at 10kV to be realised within the next year the paper examines what effect this might have on the role of Power Electronics within Power Transmission. In particular values of efficiency, weight and size are developed for 300MW PWM based HVDC converter equipment operating with both a 50Hz transformer and at 1kHz and 20kHz and concludes that with Silicon Carbide devices the cost of VSC-HVDC stations will reduce by about 30%. Changing to high frequency conversion using frequencies of up to 20kHz will result in comparable efficiencies and volumes with Si based VSC-HVDC stations, however the overall cost will increase by about 30%.","PeriodicalId":401288,"journal":{"name":"2006 12th International Power Electronics and Motion Control Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114976185","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}

One of the most critical elements in the design of this type of converters is the DC-bus capacitors. The calculus of these depends on the same factors that the same two-levels topology, and, moreover it is function of a low frequency ripple due to the current by NP point. In this work, the value of these capacitors is obtained from the analytical equations of the DC-bus voltage ripple due to the iDC (DC-bus current) and the iNP (NP current). These expressions are verified through simulation and practical results.","PeriodicalId":401288,"journal":{"name":"2006 12th International Power Electronics and Motion Control Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115471285","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}

It regulates the reactive power exchanged with the grid (up to 3 MVAR), allowing to achieve the following objectives: Network voltage regulation, reactive power compensation and power factor control. The device is composed by an IGBT based 4 level NPC (neutral point clamped) converter. The adopted modulation strategy is the space vector modulation and it takes into account the bus capacitor voltage balancing. The reactive power regulation will be carried out by a vector control technique. The correct behavior of the electronic system connected to a radial distribution network is validated in simulation. Firstly the behavior of the system is analyzed under normal operation conditions.

In this paper a control algorithm that enables STATCOM operation with unbalanced voltages is presented. The algorithm is based on the compensator mathematical model in the d-q coordinate system. In case of an unbalanced voltage sag the compensator unbalances the generated voltages to limit the negative sequence currents. The problem of low-order harmonics generation is solved with the use of appropriate switching function modulation that enables the use of a relatively small capacitor on the DC side. The proposed algorithm was tested by means of simulation of STATCOM operation in the PSCAD program.
