The digitized signals are generated at electronic instrument transformers and they are transferred to protection systems over a process bus based on IEC 61850-9-2 standard. This transferring process between electronic instrument transformers and protection systems requires a detailed performance evaluation, analysis, and compatibility of the two different systems, since various vendors' instrument transformers and relays are aimed to be connected. This paper presents a developed test facility for all-digital protection system performance evaluations. Typical power system faults are regenerated with the facility and the performance of the digital systems are investigated. The compatibility of an optical current transformer and a digital relay is analyzed. Digital relay's inverse time delay characteristics are obtained. Results show that all-digital systems provided by different manufacturers can work together and are suitable to protect power systems where protection is needed.","PeriodicalId":258632,"journal":{"name":"2009 IEEE Power & Energy Society General Meeting","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130765417","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 is seen that a large disturbance of the stator voltage will cause high transient rotor currents which trigger the crowbar protection for the rotor side converter (RSC). Once the crowbar is applied it cannot be removed until its current reaches zero. During the period the crowbar is applied, the machine behaves as a conventional FSIG, losing control of the active and reactive power. Therefore the time taken for the crowbar current to reach zero is crucial as it determines when the RSC can regain power control and how soon the AC voltage can recover. It is seen that the crowbar current can take a long time to decrease to zero and that this has a significant impact on the voltage recovery after fault. The larger the crowbar resistor and the further the generator is from synchronous speed, the shorter the crowbar current transient is. Power and energy dissipation through the crowbar resistor are also considered, and it is observed that the power varies in accordance with the maximum power transfer theorem. The detailed impact of the timings of crowbar removal and RSC reactivation on system voltage recovery is also investigated. It is seen that reactive power control during fault clearance can assist AC voltage recovery.","PeriodicalId":258632,"journal":{"name":"2009 IEEE Power & Energy Society General Meeting","volume":"32 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133040496","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 energy mix in South East Europe (SEE) is known to be a highly polluting one with important CO2 and particulates emissions. Following the introduction for several of the countries in the European Union and the signature by most of them of the Kyoto protocol, severe caps have been imposed on the CO2 emissions. Most of the SEE countries have a significant expertise in thermal combustions units based on lignite and coal. Therefore, the use of the solid biomass fuel for electricity generation has started being applied progressively as a means of electricity generation. Pure biomass plants and biomass co-firing plants are actually studied and developed in many of these countries. We refer to as solid biomass all agricultural residues, wood flakes or pellets, olive pomace and any plants that can be used as solid biofuels. Each country among the ones in SEE have different biomass type availabilities which can be transported inside the country or exported to close distances. In this article we will discuss the technologies that have already been applied in South East Europe for different types of biomass. We will stretch the point of biomass solid fuels availability, the regions that can supply important quantities and which neighboring countries can be considered in case of a shortage. The latter availability will be closely linked to the technology that is used each time and the influence of the biomass mix to the technology used. Finally, in order to describe the financial feasibility of these projects we will refer in some financing and feed-in-tariff schemes that are actually applicable.","PeriodicalId":258632,"journal":{"name":"2009 IEEE Power & Energy Society General Meeting","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133370657","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}
