Abstract: PURPOSE: A dump load trouble detection system in a hybrid generation system and a method for detecting a trouble thereof are provided to confirm easily a dump load by detecting short circuit or disconnection the dump load through a safe method. CONSTITUTION: The dump load trouble detection system includes a dump load, a first resistance, a second resistance, a third resistance, and a fourth resistance. One end of the switch is connected to a power line. The switch is used for supplying current to the dump load and blocking the current to be supplied to the dump load. One end of the dump load is serially connected to the switch. The other end of the switch is connected to the ground. The dump load includes a connecting contact. The first resistance is connected to the power line and the switch. The second resistance is connected to the first resistance and the contact between the switch and the dump load. The third resistance is connected to the connective contact of the dump load and is connected in parallel to the dump load. The fourth resistance is connected to the third resistance and the ground.

Abstract: PURPOSE: An apparatus for evaluating the performance and durability of a large bearing is provided to evaluate the performance of durability of a large bearing by testing a large bearing under the condition of a real aerogenerator. CONSTITUTION: An apparatus(100) for evaluating the performance and durability of a large bearing comprises pitch bearings(110,120), an adapter(130), a rotation unit(170), a front disc(140), and a replication body(150). The pitch bearing ha a ring gear inside. The pitch bearing reproduces a bearing for the rotation blade of an aerogenerator. The adapter is mounted between pitch bearings and operates the pitch bearing. The rotation unit engages with the ring gear to rotate the pitch bearing.
