Modeling Large Modern Fossil-Fueled Steam-Electric Power Plant And Its Coordinated Control System For Power System Dynamic Analysis, Lin Gao
Lin Gao
Fossil-fueled steam-electric power plants have many outstanding advantages and are still one of the main power types in the world especially for non-European countries. The classic mathematic models are designed for traditional hydraulic governing steam turbine units. Single turbine and its control system models are used wildly for dynamic analysis in power system. Digital electro-hydraulic (DEH) control systems and coordinated control systems (CCS) are used in most of the modern large power boiler-turbine units. They are key elements in the operation of the power station and have great impact on the system responses to the frequency or load disturbances. But …

Analysis Of Power System Frequency Responses With Hydro Turbines Incorporating Load Shedding, Lin Gao
Analysis Of Power System Frequency Responses With Hydro Turbines Incorporating Load Shedding, Lin Gao
Lin Gao
As shown in many recent works, the load-frequency behavior can be represented by system frequency response models especially for an islanding process. In this paper, a frequency response model incorporating an under-frequency load-shedding scheme is presented for islanding power system simulations. The model was applied for a realistic power system with hydro power generators. The hydro power generator model parameters were identified and similar responses were observed between the simulations and the accident records. The simulation results showed disadvantages of the primary frequency control systems of hydro power generators at the beginning of the load disturbances. The power system stability …

Conference Proceedings 3rd International Scientific Conference On “Energy Systems With It” At Alvsjö Fair In Association With Energitinget March 16-17 2010, Dr. Erik Dahlquist, Dr. Jenny Palm
Dr. Erik Dahlquist
2010 “The Energiting” is performed for the 12th time. The International Scientific conference is arranged for the 3rd time. The organisers are Swedish Energy Agency, Mälardalen University and the Research School for Energy Systems with LiU, KTH, UU and CTH. The first topic will be “Energy systems” covering use of renewable energy sources, energy conversion and process efficiency improvement with new technologies, as well as societal aspects of the introduction of new technologies. The second topic is “Energy and IT”. This covers energy and load management, interaction between production, distribution and “consumption”, usage of data for decision support and control, …
