five years of operating experience at a large utility scale photovoltaic Generating Plant
Progress in Photovoltaics, 2008Co-Authors: Larry Moore, Harold N. PostAbstract:Tucson Electric Power Company (TEP), headquartered in Tucson, AZ, currently has nearly 5·0 MWdc of utility-scale grid-connected photovoltaic (PV) systems installed in its service territory. These systems have been installed through a multiyear, pay-as-you-go development of renewable energy, with kWhac energy production as a key program measurement. This PV capacity includes a total of 26 crystalline silicon collector systems, each rated at 135 kWdc for a total of 3·51 MWdc, that have been installed at the Springerville, AZ Generating Plant by TEP making this one of the largest PV Plants in the world. This facility started operations in 2001 and recently passed the 5-year milestone of continuous operations. These systems were installed in a standardized, cookie-cutter approach whereby each uses the same array field design, mounting hardware, electrical interconnection, and inverter unit. This approach has allowed TEP to achieve a total installed system cost of $5·40/Wdc and a TEP-calculated levelized energy cost of $0·062/kWhac for PV electrical generation. This paper presents an assessment of operating experience including performance, costs, maintenance, and Plant operation over this 5-year period making this one of the most detailed and complete databases of utility-scale PV systems available to the US DOE Program.

KES - The Comparison of Characteristics of 2-DOF PID Controllers and Intelligent Tuning for a Gas Turbine Generating Plant
Lecture Notes in Computer Science, 2004Co-Authors: Dong Hwa KimAbstract:The purpose of introducing a combined cycle with gas turbine in power Plants is to reduce losses of energy, by effectively using exhaust gases from the gas turbine to produce additional electricity or process. This paper focuses on the characteristic comparison of the PID controller, the 2-DOF PID controllers, and the modified 2-DOF PID controller, in order to design an optimal controller which can be operated on the Gun-san gas turbine Generating Plant in Gun-san, Korea. The designed controllers, using various methods based on this transfer function and data have been compared to the Gun-san gas turbine system for the start-up procedure and this parameter could be used for the tuning problem.

analysis on speed governing system model for fossil fuel Generating Plant and its application in power system stability simulation
Power system technology, 2008Co-Authors: Liu ZenghuangAbstract:At present, the accuracy of the model and its parameters of speed governing system for fossil-fuel Generating Plant in power system stability simulation in China is insufficient, for this reason the frequency response process during the simulation evidently differs from the on-site accident records. In this paper, at first the authors present the prime mover energy supply system of fossil-fuel Generating Plant as well as the model of its regulating device and control mode; then analyze the impacts of these model and modes on power system stability simulation; finally, research the application of speed governing system model and point out that not only the turbine speed governing mode and parameters should be acquainted with, but also the widely used coordinated control system (CCS) of boiler-turbine and parameter setting should be learnt about.
