Load Rejection Test Of Hydro Turbine Generator On 100 L The load rejection test is most widely conducted to evaluate the transient characteristic of any generator based power systems [19, 20]. the experimentation performed in this paper is a vibrational characterisation of sg when loaded above rated loads (up to 120%) subjected to sudden load rejection.

Load Rejection Test Principle Download Scientific Diagram To perform the load rejection test the load must be switch off at the same time as the turbine is tripped, the excitation system must be in manual position and the voltage of the field winding. Load rejection test is one of the essential tests that carried out before the hydroelectric generating set is put into operation formally. the test aims at inspecting the rationality of the design of the water diversion and power generation system of hydropower station, reliability of the equipment of generating set and the dynamic characteristics of hydroturbine governing system. Reducing load or rejecting 100% load is a common operation in hydro power plant, especially within pump turbine units. when the load rejection happens, huge residual energy makes the speed of the runner rise rapidly, and the governor closes the guide vane quickly following the rules as made in advance. Hydro turbine during the transient event of load rejection. guo et al. [24] have established a numerical simulation method of different types of load rejection and reported the relationships among the different types of load rejection and their functions on the design of hydropower station and the operation of load rejection test.

The rest of the paper is organized as follows: in section 2, a novel nonlinear dynamic mathematical model of a hydro turbine generator unit is established. section 3 analyzes the nonlinear dynamical behaviors of the presented system in the process of load rejection transient. section 4 closes the paper. Severe when a sudden load rejection occurs and the generator starts to race up due to internal inertial power. a simple single line diagram explaining the basic theoretical principle behind the load rejection is shown in fig. 1 and how the frequency behaves at that time instance is in fig. 2. from fig. 1, load rejection takes place when the breaker.
