Modeling of the dynamic response of a Francis turbine [PDF]
, 2012 The paper presents a detailed numerical model of the dynamic behaviour of a Francis turbine installed in a hydroelectric plant. The model considers in detail the Francis turbine with all the electromechanical subsystems, such as the main speed governor,

Unpacking the Farmland Capitalization Effect of Ethanol Establishment
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT We unpack the impact of expansions in ethanol production—as measured by proximity to newly constructed ethanol plants and capacity expansions—on farmland values using land transaction data from Kansas in combination with modern causal inference techniques.

Investigating early warning signs of oscillatory instability in simulated phasor measurements
, 2013 This paper shows that the variance of load bus voltage magnitude in a small power system test case increases monotonically as the system approaches a Hopf bifurcation. This property can potentially be used as a method for monitoring oscillatory stability

Harnessing Digital Microstructure for Simulation‐Guided Optimization of Permanent Magnets
Advanced Intelligent Discovery, EarlyView.An experimental‐to‐computational workflow is presented that transforms experimental 3D focused ion beam‐scanning electron microscopy data into a simulation‐ready digital microstructure for multiphase functional materials. Using heavy‐rare‐earth‐free Nd–Fe–B magnets as a model system, the approach quantifies grain connectivity across complex secondary ...

Modeling and supervisory control design for a combined cycle power plant [PDF]
, 2012 The traditional control strategy based on PID controllers may be unsatisfactory when dealing with processes with large time delay and constraints. This paper presents a supervisory model based constrained predictive controller (MPC) for a combined cycle ...

Design of Hydraulic System for Pelton Turbine Governor
, 2023 Bucket turbine is a device widely used in the development of high head and small flow hydraulic energy, which converts hydraulic energy into mechanical energy. The mechanical energy output by the water turbine is converted into electrical energy through a generator and then transmitted to the user end through the power grid for use.
