In this paper, a downhole monitoring tool design method is proposed using power line disturbances. This method is based on the technology of two-way automatic communication system (TWACS). The AC current signal is used for the downhole tool. This new design scheme utilizes an external impedance connecting one phase of the ESP system to the ground on the wellhead, and a controlled thyrsitor connected between the neutral of the ESP motor and the ground by conducting at a specific firing angle and cycles. This design can overcome the impact of single-line-to-ground faults of the ESP system on the communication of downhole tools. The design method is verified through the simulation using PSCAD by case and sensitivity studies. The lab testing is conducted to further validate the effectiveness of the proposed design method.","PeriodicalId":107232,"journal":{"name":"2015 IEEE/IAS 51st Industrial & Commercial Power Systems Technical Conference (I&CPS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129571846","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}

Grid codes are published by utilities and system operators to define the requirements for interconnection of generation and other facilities to the grid. The purpose of the grid code requirements is to ensure reliability, stability, power quality, protection of equipment and worker safety. These requirements are given at the point of interconnection (POI) with the transmission or distribution system, and will be different for different sizes and types of generation. Grid codes can cover a broad range of requirements, from continuous operational constraints to behavior during contingencies such as faults. Grid codes vary considerably based upon the issuer, their country or region and the type of transmission or distribution system. Manufacturer specifications for wind turbines are generally given on a per-turbine basis at the collector system voltage. When a wind farm is proposed, an initial assessment is made of the suitability of the wind turbines to the system. Studies are performed of the grid and wind farm(s) being considered which evaluate system performance and conformance with the grid code. Finally, tests and measurements during and after commissioning verify conformance of the wind farm to the applicable grid code.","PeriodicalId":107232,"journal":{"name":"2015 IEEE/IAS 51st Industrial & Commercial Power Systems Technical Conference (I&CPS)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114708009","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}

In addition, by using mature hydroelectric power generation technology, system costs and thermal power generation unit loads can be reduced. Regarding simulating wind velocity for wind power generation, this study forecast wind velocity based on the Weibull distribution. According to wind power generation data, predicted wind velocity was converted into the amount of generated electricity. Because of the unpredictability of wind power generation, dispatch cannot be instantly performed. Therefore, pumped storage hydroelectric power generation was used to supplement wind power generation during off-peak periods by storing wind energy in the form of potential energy; thus, hydroelectric power generation supplemented thermal power generation during peak periods. Regarding thermal power generation, this study used the priority list method to calculate unit commitments and used the particle swarm optimization method to calculate economic dispatch. This study performed simulations by using thermal power generation unit, wind power generation unit, and hydraulic power data. The simulation results were compared with the results obtained from existing algorithms. The results showed that the algorithms used in this study yielded accurate results in a short time and reduced the loads of thermal power generation units in a Taiwan Power Company case.","PeriodicalId":107232,"journal":{"name":"2015 IEEE/IAS 51st Industrial & Commercial Power Systems Technical Conference (I&CPS)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133229197","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 covers applications involving service to a refinery that normally require a transformation between the utility's supply voltage and the refinery's utilization voltage. The paper specifically addresses refineries with generation that are connected to utility transmission circuits. The protection discussed must protect the refinery from the effects of utility system faults but must also protect the utility from the effects of refinery faults. Coordination between these two systems is essential to minimize the effects of fault-induced outages. This paper specifically addresses typical refinery-utility interconnections system one-line designs, determining utility supply performance expectations, impact of generation on interconnection protection, relay functional requirements for typical interconnections protection, relay communication requirements and grounding of the interconnection transformer(s) and its impact on protection.

Traditionally, the analysis is carried out based on considerations of investment cost and supply adequacy, while using a design of generators with the same rating. It does not consider the energy efficiency, thereby in some cases resulting in the generators operated at a lower efficiency under heavy loading conditions and high energy consumption. To enhance power generation efficiency and reduce energy cost, a new load analysis method for marine vessels is proposed in this paper. The relationship of operation efficiency and load factor of generators is mathematically modeled and considered in the analysis. The problem is formulated as a non-differential combinational optimization problem, where the total generation cost during a whole voyage is minimized subject to system operation and technical constraints, in order to derive the optimal generators rated power and unit commitment using genetic algorithms. The results confirmed the validity of the proposed method through load analysis of a practical ship power system, as well as energy-saving benefits using the proper generator rated power and unit commitment operation and an accurate load model for power pumps.","PeriodicalId":107232,"journal":{"name":"2015 IEEE/IAS 51st Industrial & Commercial Power Systems Technical Conference (I&CPS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126292892","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}

In this paper, key considerations on the reliability and operation of high-efficiency motors are presented, offering a comprehensive perspective on the advantages, drawbacks and limitations of high-efficiency industrial motors. A comparison of the lifetime expectancy of IE2-, IE3- and IE4-Class motors under unbalanced and distorted voltage supply is presented.
