The axial-flow impulse turbine is recently utilized for oscillating water column wave energy conversion because of its wider operating range and having no stalling point. Most previous experimental studies conducted in the oscillating air flow testing rigs can give little information of the steady-state performance of impulse turbines. A constant flow test rig was set up in this study. The steady...
Supercritical OTB (once-through boiler) units with high steam temperature and pressure have been widely used in modern power plants due to their high cycle efficiency and less emissions. To ensure the effective operation of such power generation systems, it is necessary to build a model for the design of the overall control system. There are already detailed models of once-through boilers; however,...
The pulverizing system serves an important function in the safe and efficient operation of thermal power units. The effect of coal moisture and pulverized coal moisture on the pulverizing system was considered in establishing a mass and energy balance-based dynamic mathematical model of a coal mill. The parameters of the model were identified by using the genetic algorithm and later validated with...
Recognized as an indispensable player in the future electricity supply mix of China, photovoltaic (PV) power has experienced a fast expansion in recent years. Owing to the higher cost compared with traditional coal-fired power, financial subsidy is crucial for the development of PV power. Although a series of policies have been implemented to subsidize PV power, strong and steady policies to stimulate...
At present, designing a proper bidding mechanism to decrease the generators' market power is considered to be one of the key approaches to deepen the reform of the electricity market. Based on the signaling game theory, the paper analyzes the main electricity bidding mechanisms in the electricity auction markets and considers the degree of information disturbance as an important factor for evaluating...
