Comparison of the Accuracy of Generator Dynamic State Estimation Based on the Treatment of the Governor-Turbine Mechanical Power

open access: yesIEEE Access
The availability of phasor measurement unit (PMU) data enables dynamic state estimation (DSE) of synchronous generators (SGs) via nonlinear Kalman filters. The mechanical power input of an SG is not measured by PMUs.

Linear Modeling and Regulation Quality Analysis for Hydro-Turbine Governing System with an Open Tailrace Channel

open access: yesEnergies, 2015
On the basis of the state–space method (SSM), a novel linear mathematical model of the unsteady flow for the tailrace system with an open channel is proposed. This novel model is an elastic linearized model of water hammer. The validity of the model has

Thermal Calculations for Co‐Firing of Hydrogen/Ammonia and Coal in 660‐MW Coal‐Fired Boilers

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT To achieve a clean energy transition under the dual carbon goals, blending hydrogen/ammonia into pulverized coal boilers represents a key technological pathway. Different hydrogen/ammonia co‐firing ratios (5%–50%) are investigated for their impact on the thermodynamic characteristics of 660‐MW supercritical boiler at 100% and 20% boiler ...
