The algorithm is based on the introduced graph probabilistic model taking into account the network topology, equipment state conditions, responsibility of consumers and short-circuits probability. The IEEE 14 test scheme was used as input data for a primary network while the information about secondary circuit's security was obtained from previous authors papers. The results show that the algorithm could calculate the risk of relay protection outage. To predict possible influence of relay system reconstruction it is required to change the probability indices, thus, the decrement of the system risk will be an indicator of system improvement. By comparing the risk decrement in different investment strategies it is possible to define which one is the best. The algorithm may be used for a reasonable planning of the relay protection replacement priority.","PeriodicalId":199924,"journal":{"name":"2018 17th International Ural Conference on AC Electric Drives (ACED)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128856210","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}

Booster heat pumps represent a significant share among them. A duty cycle of a booster heat pump depends on a specific load profile. The research is devoted to the problems of calculation and interpolation of the efficiency of the synchronous reluctance electric drive in booster heat pump. In order to estimate the pump unit performance, a semi-analytical model on the basis of experimental data on the selected operating modes is used. The various approaches of interpolation error estimation based on the data of synchronous reluctance motor drive efficiency are described and estimated.","PeriodicalId":199924,"journal":{"name":"2018 17th International Ural Conference on AC Electric Drives (ACED)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121917196","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}

Since the permanent magnets as well as the excitation winding are mounted on the stator, cooling can be performed easily. Also, the usage of slip rings can be avoided. A simple rotor structure employs the possibility to operate the machine in a high speed range. This paper presents two types of flux switching machines with hybrid excitation.

Here we consider the case of a start with a constant rotational speed of the stator magnetic field. For high-inertia drives, the starting process is very long and can be accompanied by a significant motor overheating. Analytically, as well as using computer simulation, the following is shown: — The larger is the motor size (with other things being equal) — the stronger is the problem of heating the rotor winding in the starting modes; — The lower is the rated motor speed with the same power and the same mechanism, the less is the heating of the rotor winding in the starting modes (at gear ratio of the gearbox corresponding to the rated motor speed and the required speed of the mechanism); — By adjusting the acceleration time when starting an induction motor with thyristor voltage converter it is impossible to solve the problem of the rotor winding overheating.","PeriodicalId":199924,"journal":{"name":"2018 17th International Ural Conference on AC Electric Drives (ACED)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127676243","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}

Statistics of the household's electric current and the corresponding neutral conductor's voltage is obtained during a two months period.

Based on the research presented in this paper, an augmented approach was developed to determine expected generation capacity deviations in power system with a high penetration of solar power plants.

It is based upon the spectral analysis of harmonic current and conductancies along the air gap which is applicable to any electric machine with a magnetic non-symmetry of a rotor and combines the method of winding functions and the energy method of obtaining the electric drive's coordinates (MDS, induction, EMF, electromagnetic torque). In addition, it also allows one to search for the optimal shape of current according to the principle of the electric machine operation. Under this algorithm it is recommended to perform optimization calculations under the following assumptions: the converter is not saturated, steel magnetic conductivity is equal to infinity, and there are no scattering fluxes.
