In this paper, the detection method of high-frequency partial discharge sensor performance characteristics is studied. The detection principle and method of transfer impedance and detection frequency of high-frequency sensor are introduced. The test platform of sensor performance characteristics is established. In this paper, the effects of two wiring modes on system testing are studied. The results show that both wiring methods can meet the requirements of high-frequency sensor performance testing. Through the comparison results of high-frequency partial discharge sensors from different manufacturers, the transfer impedance and detection frequency of imported high-frequency sensors are better than those of domestic equipment. The performance research of high-frequency partial discharge sensor is of great significance to the network access, arrival acceptance and periodic calibration of the high-frequency partial discharge detector, and provides a strong technical guarantee for the on-site testers.","PeriodicalId":387293,"journal":{"name":"2019 4th International Conference on Power and Renewable Energy (ICPRE)","volume":"14 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":"132612508","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}

Based on the principle of pulse current method, the EPR cable sample discharge of simulated scratch defects is measured every 20 min at 35 kV, and at the same time, partial discharge pulse time domain spectrum is collected. The time domain characteristics of discharge pulse with discharge durations of 60 min, 140min, 220min and 300 min were analyzed separately. The discharge pulse oscillation wave extracted from the spectrums were analyzed, and the positive and negative pulse fall time $mathrm{T}_{r}+(-)$ of each pulse oscillation wave was analyzed and rise time $mathrm{T}_{f}+(-)$, pulse width $mathrm{T}_{mathrm{w}}+(-)$, duration Ti, pulse peak absolute value p, etc., respectively calculate the difference in the same characteristic quantity of the oscillation wave at different discharge times. In addition, the starting frequency, cutoff frequency and rms bandwidth of the oscillating wave power spectrum are studied. The results show that during a power frequency cycle, as the discharge time increases, the discharge pulse of the positive half cycle gradually shifts to the left; the oscillation attenuation rate is faster, and the discharge intensity is continuously enhanced; $mathrm{T}_{r+}, mathrm{T}_{mathrm{w}+}, mathrm{T}iota$ and p have lager degrees of difference in different discharge times; the initial frequency, cutoff frequency and rms bandwidth of the power spectrum increase with the increase of discharge time, and the maximum increment is from 140 min to 220 min. Comprehensive analysis of the partial discharge pulse characteristics provides a basis for further evaluation of the EPR cable operating state.","PeriodicalId":387293,"journal":{"name":"2019 4th International Conference on Power and Renewable Energy (ICPRE)","volume":"92 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":"128850438","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}

For this purpose, unit root analysis has been conducted employing, among others, augmented dicky fuller-generalized least squares test. Based on the order of integration, the Johansen Juselius (JJ) cointegration testing has been employed to confirm the existence of long-run, which is followed by vector error correction model (VECM) to calculate short-run Granger causality analysis. The empirical findings unearthed the bilateral causal connection between aggregated energy use and economic performance, renewable energy generation and economic performance, and human capital and economic performance. Thus, it confirmed the existence of feedback effect for aggregated energy use, renewable energy generation, and human capital in their relation to economic performance. However, a unilateral positive causal connection is revealed running from renewable energy generation and human capital to aggregated energy use, and from human capital to renewable energy generation in both the long-run as well as short run. Additionally, the causal association running from aggregated energy use and renewable energy generation to economic performance has been exposed in the long-run as well as short-run, hence supporting the growth hypothesis. The findings signified the importance of enhanced generation of renewable energy along with the promotion of aggregated energy use for economic performance in Pakistan.","PeriodicalId":387293,"journal":{"name":"2019 4th International Conference on Power and Renewable Energy (ICPRE)","volume":"21 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":"114678068","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}

Due to the inherent volatility of new energy, accurate prediction of generation power can effectively reduce the impact on the electricity grid system. In order to improve the prediction accuracy, a dynamic meteorological element correction method considering multiple meteorological elements is introduced, and a centralized power forecasting platform is established. At the same time, due to the frequent occurrence of extreme weather events in recent years, such as wind fan icing, lightning gale, hail, mountain torrents and so on, all of them have brought challenges to the safe operation of new energy power plants, so a fan icing warning model has been developed. Based on the Internet automatic published information plantform of meteorological disaster has established which greatly reduced the loss of power plants caused by the extreme weather.","PeriodicalId":387293,"journal":{"name":"2019 4th International Conference on Power and Renewable Energy (ICPRE)","volume":"31 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":"127147882","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}
