Harmonic AnalysisHarmonic analysis has become more important due to the application of AC & DC adjustable speed drives, converters and other equipment that produce harmonic distortions. These non-linear loads generate harmonic currents that interact with system impedances. These interactions may result in equipment malfunction and/or damage to the power system. A GE harmonic study analyzes the system and recommends corrective measures, which include the design of filters or traps to absorb harmonic currents generated by non-linear loads. Conceptual Design StudyThe purpose of a conceptual design study is to develop a roadmap for building and maintaining an optimum power system that serves present and future plant operating needs. Conceptual design studies often include a comprehensive review of the existing system with a clear understanding of future requirements. A key component of a conceptual design study is the ability of the engineer to understand existing conditions, future needs and equipment and system capabilities. A combination of load flow, motor starting, short-circuit, protective device coordination and stability study techniques will be employed to complete the design study. Motor Starting StudyThe motor starting study analyzes the motor, the motor load and the connected power system through the range of operation. Recommendations on motor starting methods are provided. Impact Load StudyAn impact load study can model the system to determine whether the impact load may be added to the existing system without causing detrimental operating effects due to voltage and frequency fluctuations. Power System Automation StudyAs an extension of a conceptual design, protective device coordination, and load and power factor studies, the power system automation study focuses on developing solutions to operating issues in existing or planned power systems. It recommends electronic and control technologies that provide productivity enhancing solutions. Diagnostic StudyA diagnostic study provides an engineering review to determine the root cause of power system failure. The power systems studies GE offers are tailored to meet the needs of the individual facility and customer. Each study involves the collection of data and information. GE employs the most advanced tools, processes and procedures to obtain information. The end result is a formal, comprehensive report outlining study findings and recommended actions. |
