In the past year, Constellation Power Source Generation (CPSG) has commissioned (or is commissioning) four new combined cycle and simple cycle gas turbine plants. Each of these plants involved different equipment, vendors and architect engineers. Acceptance testing was done for these plants in accordance with ASME PTCs 46 and 22 with support from Fossil Consulting Services, Inc. (FCS). The Performance Test Codes provided the framework for the testing done, but considerable work was required to apply the codes in accordance with relevant contracts. Problems in acceptance testing can result in costly delay and retesting. This paper describes the lessons learned in resolving issues and problems that can help others in planning for and executing similar tests. These lessons learned can also help in writing effective contracts between owners, vendors and architect engineers.

The purpose of this paper is to introduce, examine, and evaluate the industrial experiences and effectiveness of a Thyristor Controlled Series Compensator (TCSC) replica controller installed in Korea in 2019 through a review of its configuration, test platform, and practical application, and further to propose operational guidelines for replica controllers. Four representative practical cases were conducted: a Dynamic Performance Test (DPT) under a sufficiently large-scale power system prior to the Site Acceptance Test (SAT), pre-verification for on-site controller modification during operation stage, parameter tuning to mitigate the control interaction, and time domain simulation for Sub-Synchronous Torsional Interaction (SSTI). None of these four cases can be performed in a Factory Acceptance Test (FAT) or on-site. Therefore, TCSC control performance was accurately verified under the entire Korean power system based on a large-scale real-time simulator, which demonstrated its effectiveness as a powerful tool for operations including multiple power electronics devices. Our review herein of these four practical cases is expected to show the usefulness of replica controllers, to demonstrate their strength to deal with practical field events, and to contribute to the further expansion of the application area from a perspective of electric utility.

Test Result

Performance acceptance test for gas-steam Combined Cycle Power Plant (CCPP) is of great significance for both equipment manufacturer and customer. The influence of measurement error on the calculation of guaranteed performance data as power output and heat rate can lead to unnecessary loss for either party. Commonly used uncertainty analysis method based on ASME PTC 19.1 would require all measuring instrumentation working at designed accuracy range. Meanwhile, due to the complexity of CCPP system and large number of measuring items, and as well the propagation of measurement and data reduction error, the uncertainty of corrected performance data could be significant. In this paper, process data reconciliation method based on VDI 2048 is introduced. With access to complete performance test data from a CCPP project, data reconciliation calculation is performed with an appropriate thermodynamic model. Several measurement values with gross error are identified and verified in heat balance calculation. Moreover, after recalculating with the reconciled data instead of raw data for the corrected power output and heat rate, comparison with the common uncertainty analysis method is also carried out. It is shown that with this reconciliation method, it is not only possible to find out gross errors such as instrumentation drift, but also able to dramatically increase the test result accuracy, which is of great value for both manufacturer and customer.

Nowadays, Power Dispatching System is not only facing disturbances caused by electrical data, but also facing disturbances caused by non-electrical data, such as working conditions and communication failures. Currently applied power system simulation software is either only facing monitoring personnel or only facing some application functions, without comprehensive consideration of the disturbance environment brought by the Power Dispatching System itself. This disturbance may reduce the reliability of Power Dispatching System, and even have a great impact on its reliable operation. This paper proposes a simulation system used as building disturbance environment for the test of Power Dispatching System. It proves that the established environment could effectively test a variety of functions of Power Dispatching System under the following situations, normal operation, disturbance, fault and avalanche. By applying this system, some functional and performance test that could not be done in Factory Acceptance Test (FAT) can be implemented, thus can be used to assist on Power Dispatching System’s security test.

This paper focuses on making some review and observation on the performance of equipment named Mass Properties Measurement System (MPMS) which capable to calculate the center of gravity (CG), moment of inertia (MOI) and Product of Inertia (POI) of a satellite. Before approving to receive such a huge machine/equipment consist of mechanical and electronic structure, National Space Agency (ANGKASA) which acts as a Malaysian Government Agency has to go through an Acceptance Test Procedure (ATP) to compare with the factory acceptance result on its performance review. The Factory Acceptance Test (FAT) for this machine has been done earlier in United States (USA) as the equipment is manufactured in Connecticut, USA. This ATP is responsible on determining the requirements of a specification or contract are met or not by conducting test which is commonly applied for engineering and its various subdisciplines and the test have been witnessed by a Malaysian Research Institute; SIRIM Berhad, local and international contractors as well as the principal or manufacturer of the equipment itself and took place in ANGKASA, Banting, Selangor. It may involve chemical tests, physical tests, or performance tests by comparing the results with FAT [1].POI-1000M Rotary table, a rotor, deadweights, a compressor and a beam are the main components to be used for the acceptance performance test assisted by a control system for operators to calculate the desired measurements. Results confirmed that the ATP and FAT results are finally been compared and the equipment is successfully approved.

Circulating flow in front of open and covered intake systems in many cases is the initial point of free-surface vortex formation. Depending on the strength of the circulation air pulling vortex formation up to a coherent air core will appear starting at the surface leading directly to an installed pump inside the intake. Thus the mechanical load of the pump will increase and the hydraulic performance will be degraded. Furthermore, pre-rotation of the fluid close to the suction bell can be forced up to limits which are not in compliance to state of the art acceptance criteria. At least non-symmetric velocity distribution at the impeller will arise out of this flow conditions. Within physical model tests intakes together with pumps can be optimized for their best efficiency point of operation. Flow conditions can be achieved generating kinematical affinity at the suction bell which are close to the conditions of the acceptance test. The report shows application oriented solutions for the installation of cost effective flow guiding devices in open and covered intake systems to assure adequate pump performance. Test results of model investigations and experiences by modifying intake structures of existing plants will be presented. Concerning the sensitivity of high specific speed vertical pumps approach flow conditions especially at the intake structures have to be in accordance to state of the art acceptance criteria to assure adequate availability of the pumps. By today it is common practise and state of the art to test the behaviour of intake and outfall structures by physical model tests.

This paper presents the continuation of the work performed during the development of an uncertainty analysis method for estimating error levels in data gathered during factory aero-performance acceptance tests of centrifugal compressors. The previous work incorporated the effects of the variation and uncertainty levels associated with every parameter used in the calculation of centrifugal compressor aero-thermal performance. The work discussed herein focuses on the effects of the variation and uncertainty levels associated with the key measured variables, which are the parameters identified as having the greatest effect on the uncertainty of the performance measurements. Also included in this work is an evaluation of the effects of the correlated bias uncertainty components associated with said key variables, as well as comments on how these effects can be harnessed to reduce the uncertainty of the test data. The evaluation is performed via parametric studies, which present the test uncertainty levels achievable as a function of different correlation levels between the systematic uncertainty components of the measured data. Two different methods are used for the analysis of data measured for several machines. The first method is based on the direct use of the Monte Carlo simulation technique combined with real gas equations of state. The second method employs uncertainty propagation equations and the methodology included in the ASME PTC-19.1(1998) test code. Both approaches use the polytropic compression model and equations for performance evaluation included in the ASME PTC 10 (1997) Power Test Code. Data gathered during an on-site acceptance test of a centrifugal gas compression package are used to illustrate the effects of the uncertainty in the knowledge of the gas composition handled by the compressor over the uncertainty levels that can be obtained with this type of tests.

The purpose of this article is to propose 4 dimensions for consideration in hearing aid fittings and 4 tests to evaluate those dimensions. The 4 dimensions and tests are (a) working memory, evaluated by the Revised Speech Perception in Noise test (Bilger, Nuetzel, & Rabinowitz, 1984); (b) performance in noise, evaluated by the Quick Speech in Noise test (QSIN; Killion, Niquette, Gudmundsen, Revit, & Banerjee, 2004); (c) acceptance of noise, evaluated by the Acceptable Noise Level test (ANL; Nabelek, Tucker, & Letowski, 1991); and (d) performance versus perception, evaluated by the Perceptual–Performance test (PPT; Saunders & Cienkowski, 2002). The authors discuss the 4 dimensions and tests in the context of improving the quality of hearing aid fittings.
