Its operation began when the intensity of solar radiation exceeded the value of several dozen W/m2 and lasted up to several W/m2. During the energy conversion in PV power plant, the average daily temperature of photovoltaic modules fluctuated in the range from -10°C up to 51°C. Based on the data collected regression models have been developed that explained changes in the amount of electric energy generated in non-silicon PV modules, depending on the available solar radiation energy and PV modules temperature.","PeriodicalId":288282,"journal":{"name":"2019 Applications of Electromagnetics in Modern Engineering and Medicine (PTZE)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116691414","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}

A method of maximum power point tracking for a variable speed wind turbine system 变速风力发电系统最大功率点跟踪方法

The method does not require knowledge on the turbine parameters, power coefficient characteristics $C_{p}(lambda)$ nor air speed and density. The algorithm searches for the generator peak power by varying the angular speed and observing if it results in increment or decrement of the output power. The operation is repeated iteratively in the direction of the power growth until the peak power point $d P / d omega = 0$ on the $P (omega)$ curve is reached. The speed reference calculated by the algorithm is used to modify the generator reference torque. The main difficulty is that $P(omega)$ curve and the peak power point vary with the wind speed so the algorithm may wrongly recognize current position on the power curve. Illustrative Matlab/Simulink simulations carried out for a 40 kW fixed pitch wind turbine data are presented to verify the presented algorithm.","PeriodicalId":288282,"journal":{"name":"2019 Applications of Electromagnetics in Modern Engineering and Medicine (PTZE)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114998115","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}

At the selected workplace there are installations that protect employees and allow for safe work. These include circuit breakers, residual current devices and surge arresters. Appropriately designed and constructed installations, the correct manner of their use and protection of workers guarantee both - the safety of employees and the correct operation of machines. In the working environment, the use of machines supplied from the mains causes that employees are often subjected to the influence of electromagnetic fields emitted by these devices, being unaware of it. The purpose of the conducted research was to analyze the hazards present in the fish and vegetable processing plant and to conduct measurements on the electromagnetic field emitted by selected devices in the production hall. It was aimed at reassuring employees that their work environment does not expose them to additional hazards associated with the impact of fields with values exceeding the limit. The test results confirmed that the values of emitted fields do not exceed the norm and the electromagnetic field does not threaten the safety and health of employees.","PeriodicalId":288282,"journal":{"name":"2019 Applications of Electromagnetics in Modern Engineering and Medicine (PTZE)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128864634","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}
