Due to the synchronous operating nature of a PM motor, most motors of this type are used in combination with a variable frequency drive (VFD). PM motors capable of direct on line (DOL) starting have been manufactured for over 30 years [2], but the application of this technology has historically been limited to low horsepower, niche applications. In an effort to provide motors with higher than premium efficiency levels, this technology is now making its way into much larger motors. This paper discusses the transients associated with DOL starting this type of motor and the potential challenges they pose. These include transient torque, inrush current and corresponding dips in voltage. The same issues exist with induction motors and comparisons of the two technologies are offered. In addition, the ability to synchronize a given load must be considered. Test results from line starts of this type of motor are presented. Various techniques to diminish the effects of the starting process, including application guidelines, are discussed. Ongoing efforts to establish industry standards for this type of motor are reviewed.","PeriodicalId":264800,"journal":{"name":"2014 IEEE Petroleum and Chemical Industry Technical Conference (PCIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126396258","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}

With voltage distortion often exceeding 20%, equipment associated with the drilling operation can experience erratic operation and equipment damage. Repeated damage to one or several AC Drives is common. One land Rig in Northern Alberta was experiencing failures with its centrifuge equipment on a weekly basis. During one visit to the site, a Drive in the centrifuge was found to have tripped off causing the centrifuge to plug up. After cleaning out the centrifuge and restoring the Drive, it tripped off again shortly after drilling operations resumed. A Power Quality Analyzer was connected which revealed extremely high levels of voltage distortion during drilling operations. Deep notches, visible in the voltage waveform, were found to be the result of SCR's in the mud pump DC Drives. Total harmonic voltage distortion (VTHD) reached 25%. A series connected passive filter was installed ahead of the centrifuge equipment to reduce the voltage notching and lower voltage distortion. The filter reduced notch depth by more than half and lowered overall voltage distortion at the centrifuge panel to <;9% during the most severe drilling operations. With line side voltage distortion levels remaining in the 20% range, the filter proved to be extremely effective in eliminating all centrifuge operational and premature failure issues.","PeriodicalId":264800,"journal":{"name":"2014 IEEE Petroleum and Chemical Industry Technical Conference (PCIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133602436","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 paper describes the isolated system and the methods used to model the electrical and mechanical system. The system models the mechanical compressors with torque pulses which are translated into the electrical system as current pulsations and then through the generators and onto the generator/turbine mechanical system as power oscillations. These oscillations can impact the shaft torsional modes of the turbines/generators and this impact is detailed in this paper. The key to this evaluation was the integration of the electrical synchronous machine models with the mechanical system models. The validity of the turbine torsional model was critical and was checked against the manufacturer's model used for the turbine design. The paper reviews various options to mitigate the impact of the power oscillations and compares the effectiveness of each option. Several operating modes are evaluated for the oscillation frequency and magnitude of torque and power impact on each generator/turbine. The results of each mitigating option and various operating modes are detailed in the paper.","PeriodicalId":264800,"journal":{"name":"2014 IEEE Petroleum and Chemical Industry Technical Conference (PCIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127986396","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 adds cost and can increase fault levels. IEEE Std 141-1993 provides guidelines on how to size electrical equipment but, at the early stage of the project, when the equipment is being purchased, much of the process information necessary to properly size the equipment is preliminary at best. Also, much is left to the discretion of the individual design engineer, who is often not an employee of the facility's eventual owner and, therefore, may have no incentive to reduce equipment size. In fact, depending upon the contractual relationship and due to the preliminary data, compressed schedule, and long delivery, design engineers tend to oversize the equipment. This paper describes an approach for establishing a load-based upper size limit to control oversizing of electrical equipment. The paper will demonstrate that establishing this upper limit can effectively control oversizing of the electrical equipment with information available at the early stage of the project. The resulting safety and economic benefits of the properly sized electrical equipment cascade throughout the power system.","PeriodicalId":264800,"journal":{"name":"2014 IEEE Petroleum and Chemical Industry Technical Conference (PCIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128606992","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 end user obtains baseline data for condition monitoring performed during the machine's operating life. The design geometry of stator windings and manufacturing processes used to produce them will affect the dielectric test results. There is a significant challenge in comparing test results from different stators to obtain a statistically useful sample for an acceptance test database. This paper compares dielectric test results from the 14.4-kV windings of several new 1800 rpm, 26.1 MW (35000 hp) centrifugal compressor synchronous motor stators of identical design, built for two US chemical plants. The results are compared to those from accompanying sacrificial coils. The stator diagnostic tests include dissipation factor (DF, or tan delta), power factor tip up (PFTU, or delta tan delta), offline partial discharge (PD), corona inspection with a UV analyzer, and online PD. Sacrificial coils produced and processed alongside each stator received the specified API coil acceptance tests, plus corona inspection with a UV analyzer. PD measurements on the sample coils were repeated at elevated voltage, and the results compared to the corona inspection observations. The paper shares the comparative analysis of the stator- and coil test results as an excellent example of baseline FAT data.","PeriodicalId":264800,"journal":{"name":"2014 IEEE Petroleum and Chemical Industry Technical Conference (PCIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124409192","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}

This is due to the increase in the number of electrically driven loads and the severe space and weight restrictions offshore. The same is being seen now for onshore installations where there is often limited space for new production facilities. Expansion of existing plants results in both increased rated and short-circuit currents, and in some cases more complex switching arrangements, some of which could cause switchgear ratings to be exceeded. There are several techniques that can be used to cope with such situations. In some cases it is sufficient to provide interlocking to prevent unacceptable operating conditions from occurring. In other cases it is necessary to add pyrotechnic fault current limiters (FCL) to prevent equipment destruction should a short circuit occur. As with all equipment, it is necessary to understand how FCLs operate in order to be sure that they are correctly integrated into the power system. This paper will review several techniques that have been used in applications to ensure switchgear integrity. There is a special focus on the correct integration of FCLs. The authors consider such measures to be an integral part of the switchgear thus allowing verification of all safety features during the equipment design and testing phases prior to arrival at site. The project specifications should include all planned future growth to ensure that the power system and switchgear be designed accordingly.","PeriodicalId":264800,"journal":{"name":"2014 IEEE Petroleum and Chemical Industry Technical Conference (PCIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132223801","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}
