To solve the problem, for the industrial PMSM without the requirement of running the motor for a long time at low speed, this paper proposes an improved 3-step startup method. The robustness, stability and response rapidness of the proposed method are discussed in detail, particularly for the transition process switched to the speed feedback control with sliding mode observer (SMO). In order to achieve a smooth transition, parabolic declining function and initial integral value selection are introduced. Simulation and experimental results on a 2.7-HP PMSM drive confirm the correctness of the proposed startup method.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128005371","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 topology of IEEE 118 bus system is assumed as DC power flow and used to verify the proposed algorithm. The conducted simulation shows the proposed algorithm achieves fast convergence rate and small steady-state error.

This work proposes a low-cost and open-source tool, which presents the required features for testing protection schemes based on IEC 61850. The results show that our tool can follow progressive transmission intervals of GOOSE messages.

By establishing the small-signal model and analyzing the power relationship between different parts, a balanced charging control strategy by adjusting the battery states of charge (SOC) of each phase, bridge arm and the sub- module is proposed, the core of which is the MMMC bridge arm current control strategy.

This study proposes a Deep Neural Network (DNN) framework which integrates meteorological satellite images with historical PV power output data to conduct short-term PV power prediction (2-hour ahead). For this study, Communication, Ocean, and Meteorological Satellite (COMS) was used, and the proposed model was evaluated on test sites in Yeongam and Jindo, South Korea. The proposed DNN model was able to consider the variations of atmospheric condition and successfully learn the complex meteorological patterns by using multi-temporal COMS satellite images stacked with historical PV data. The experiment on historical PV power output, compiled over three years from 2015 to 2017, confirms that the integration of multi-temporal satellite images is more accurate than using single mono-temporal satellite image in short-term PV power prediction.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130204095","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}

HVDC technology is increasingly used for bulk power transmission due to advantages like low loss, ease of control, etc. However, the protection system for the HVDC system is not as mature as AC system. HVDC system requires fast and accurate fault detection. Recently, various time- and frequency-domain algorithms are proposed. In this paper, Stockwell (S-) transform is utilized for real-time fault detection. Different type of faults in HVDC transmission line are simulated using PSCAD. The generated fault signals are analyzed using MATLAB. S-transform can detect the transient signal effectively in time-frequency domain.
