The two outputs of the proposed converter can be connected in series or parallel to share the large load current or voltage according to the load condition. Therefore, the voltage and current stresses of the secondary rectifiers can be significantly reduced and the VA rating of the main transformer can be halved compared with the conventional current-driven phase-shift full-bridge (CD-PSFB) converter. The conduction losses are also greatly reduced especially at output-parallel and large load current condition. Therefore, the proposed converter would be a good candidate for wide constant power range applications. The current and voltage sharing performances are also analyzed and finally the simulation results have validated feasibility of the proposed converter.","PeriodicalId":387293,"journal":{"name":"2019 4th International Conference on Power and Renewable Energy (ICPRE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115703251","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}

Once it fails, it will seriously threaten the safety of the power grid. In this paper, a new high-voltage circuit breaker fault diagnosis algorithm based on denoising-stacked autoencoder is proposed. Firstly, the acceleration sensor is used to collect the vibration signal of the high voltage circuit breaker. The high voltage circuit breaker fault signal data are collected during equipment failure in the laboratory simulation experiment and site field operation. This non-stationary random vibration signal is then denoised and processed using the Hilbert-Huang transform. Since the on-site vibration signal is derived from data from different voltage levels and equipment manufacturers, it is necessary to clean the data firstly. Finally, the denoising-stacked autoencoder is used to perform automatic feature extraction and pattern recognition classification on the preprocessed data. Automatic feature extraction reduces the dependence of traditional artificial feature engineering on expert knowledge as much as possible, and makes full use of fault features, thus improving the accuracy of diagnosis and the generalization ability of the model.","PeriodicalId":387293,"journal":{"name":"2019 4th International Conference on Power and Renewable Energy (ICPRE)","volume":"VII 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130729443","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}

Installed capacities and consequences of the intermittency of RES electricity are compared to the demand. Complete grid data for Germany on a 15min time grid are analyzed for the years 2015 to 2018 with SPSS and MATLAB scripts. The capacity factors of RES-systems are determined and found to be in the 10% to 20% range. The probability distributions of electricity demand and available RES-electricity differ qualitatively and the correlation of both quantities is low. To investigate potential back-up capacities for RES-electricity, duration and the frequency of events were determined, when renewables electricity production is below certain thresholds of the total demand. Around 200 such events occur per year, their average duration is around 8h and longest phases observed are around 40h.","PeriodicalId":387293,"journal":{"name":"2019 4th International Conference on Power and Renewable Energy (ICPRE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131245939","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}

However, most of the distributed PV arrays are single-phase, so there are lots of differences between the output power of each phase, which exacerbates the three-phase power unbalance problem in rural power grid. In order to solve this problem, this paper proposes a new topology in which the grid-current is controlled by an DC-AC converter of each phase and PV inverters are connected to the grid in series. After adopting series connection, the adjustment is more flexible and effective and the three-phase power unbalance problem can be solved more pertinently because the single-phase line is controlled separately. Finally, a simulation model is built in MATLAB and the simulation results fully prove the effectiveness of this topology.","PeriodicalId":387293,"journal":{"name":"2019 4th International Conference on Power and Renewable Energy (ICPRE)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116886101","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}

Most industries are dependent on electricity and different electrical equipment and, as a result, maintaining energy quality has become a major issue for all industries to flourish and profitably. The Distribution Static Synchronous Compensator (D-STATCOM) is an advanced device-based power electronics device that can be used to control the power flow of distribution lines.Space Vector Pulse Width Modulation (SVPWM) is an advanced, intensive computational PWM method. In this paper, SVPWM technology based on Particle Swarm Optimization (PSO) is used to avoid the computational complexity used in traditional implementations. The integral proportional controller is adjusted by means of a particle swarm optimization (PSO) algorithm to improve the response performance of the switch angular. In the design of the PSO algorithm, adjust the Pi controller parameters kp and ki, so that the switching angle can achieve the best parameter values.PSO is required to determine the optimal switching angle while maintaining the base voltage, which can reduce some of the higher harmonics. To promote this technology, it can be extended to multi-stage inverters. When any loading effect, the structure of the system can be introduced to restore the bus voltage, and the control algorithm using the PSO controller effectively control the amount of power without problems under fault conditions. The simulation results show that the new D-STATCOM based on SVPWM can achieve better control and improve system efficiency.","PeriodicalId":387293,"journal":{"name":"2019 4th International Conference on Power and Renewable Energy (ICPRE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127510479","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}
