Numerical results have been demonstrated that the ICS algorithm is efficient in locating faults on the distributed parameter transmission lines of the power system, as well as achieve satisfactory performances. Additionally, the results of using the ICS algorithm are also compared with those of using other existing algorithms showing the superiority of the proposed algorithm in the fault location application.","PeriodicalId":6677,"journal":{"name":"2019 2nd International Conference on High Voltage Engineering and Power Systems (ICHVEPS)","volume":"122 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85643551","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 proposed modified dc-dc Cuk converter has an advantage compared to the conventional dc-dc Cuk converter. The output voltage polarity of this proposed converter is not reversed as in the conventional dc-dc Cuk converter, while the input and output currents are continuous similar to the conventional dc-dc Cuk converter. To control the proposed converter, a simple double loop controller is used. The outer loop controller is controlling the output voltage and the inner loop controller is controlling the inductor current. The inner loop and the outer loop are designed as propotional-integral (PI) control. The analytical approach for designing the control scheme is conducted by linearizing the small-signal model of the proposed converter to form the inductor current and output voltage transfer functions. These transfer functions will be analyzed by using phase and gain margin aproach to obtain the control parameters (Kp, Ki, and Ti). Simulated and experimental results are included to show the validity of the proposed concept.","PeriodicalId":6677,"journal":{"name":"2019 2nd International Conference on High Voltage Engineering and Power Systems (ICHVEPS)","volume":"53 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73570848","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 of the oil and gas companies adopt the sub-tropical lightning characteristic for the protection of their facilities such as IEC, NFPA, etc. and these standards are applied by companies, consultants and engineers to many structures and facilities in Indonesia. Due to these tropical weather condition, tanks and refinery are not inherently self-protected against lightning direct strikes, they need additional protection to prevent direct strike to tank's metal skin, breather valve at the top of tanks and automatic tank gauging (ATG). Statistically, almost every year the tank is hit by lightning in Indonesia and burn out. An innovation technology calls extended mast terminal (EMT) and free-standing mast (FSM) are used to protect tanks and refinery from lightning direct strikes. A tank was directly hit by lightning and burn out in PT Pertamina EP Asset 5 Sangasanga area at East Kalimantan since in-proper lightning protection system was applied.

It is also reported that the aging defect, i.e., deposits would be due to the deoiling of the silicone grease or oil, exuding chemical additives such as vulcanizing additives from SRC, from dismantlement observation of the decommissioned XLPE terminations. Such defects might easily ignite partial discharge (PD) combined with the formation of the delamination due to the thermal stress under its operation and finally lead to failure. In this paper, PD characteristics are discussed for the XLPE cable termination using void defect model. Then, an epoxy resin mixed with barium titanate is injected to the interface of the SRC and the XLPE cable, and its PD characteristics are investigated. Barium titanate is one of the highest ferroelectric materials and considered to be a suitable material to simulate the aging deposit. The PD characteristics are discussed from viewpoints of the number of pulses, maximum charge and PRPD pattern. From the experiment, it is revealed that barium titanate layer can affect electric field behaviour inside the SRC interface with the relatively stable condition of PD occurrence during observation, especially in the border area of semiconductive and insulation of the SRC.","PeriodicalId":6677,"journal":{"name":"2019 2nd International Conference on High Voltage Engineering and Power Systems (ICHVEPS)","volume":"19 1","pages":"196-201"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83293877","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}

It compares measured current from two relays that installed on each substation. The two relays \"talk\" to each other using certain communication media, e.g. optical fiber, pilot wire, etc. Communication is one of the important components that greatly determines the reliability of the LCD relay. Without proper communication media, this relay cannot work as a protection system. No matter how sophisticated the media is, sometimes experiences communication failure. And this condition is very risky because it can lead to widespread power outage if a system failure occurs on the related transmission line. Recently, many of our transmission lines are provided LCD relay as main protection, OCR/GFR as local backup protection, and Z2/Z3 Distance relay as remote backup protection. If there is system failure on the transmission line, LCD would trip instantaneously to shutting down the line. However, if a system failure occurs when LCD communication failure, LCD would be blocked and the line would be shutting down by remote backup which has delayed for fault clearing time. It can cause more impact such as widespread power outage or equipment damage. This paper deals how to provide instantaneous protection function while LCD blocked by communication failure. This paper shows the implementation of automatic function switching to activate Z1 distance function while communication failure detected. This Z1 would operate as main protection while LCD blocked and whenever occurs a system failure on the transmission line, this protection would detect and clear fault instantaneously. Thus, widespread power outage and equipment damaged can be avoided.","PeriodicalId":6677,"journal":{"name":"2019 2nd International Conference on High Voltage Engineering and Power Systems (ICHVEPS)","volume":"24 1","pages":"227-229"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80213980","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}
