For the testing of Turbine Valve Hydraulic Actuators, the hydraulic actuators do not disconnect from the grid. Instead, it uses the test block for removable testing and analysis of the hydraulic supply and measurement system. A technology has also been developed for predictive diagnostic algorithms and the preventive maintenance level of performance diagnostics exam (inside-of-the-cylinder leakage test and dump seat leak test). The said technology makes use of hydraulics and test algorithms, data analysis, and predictive diagnostics. The configuration technology, on the other hand, uses the hydraulic actuators to predict system performance diagnostics, through a preseparation health assessment. Aside from these, the conservation prevention techniques of the field test is also removable.
The tester technology includes hydraulic data analysis and forecasting diagnosis algorithms to evaluate
the soundness and forecast hydraulic actuator diagnosis.
The Turbine Valve Actuator Tester (TVAT) was successful in a field test performed at the Korean power company, KOSPO, in May 2012. It successfully commercialized and received favorable customer feedback. It was also selected as a prior purchase recommendation product by the patent office of Korea.
TVAT is the only product that was able to test its Turbine Valve Actuators in workplaces and actually has multiple patents.
The test is necessary for the reliable supply of electrical power and safety, especially with the current global increase of power plants.
TVAT improved on the separation problem of the Turbine Valve Actuators from the hydraulic system for diagnosis and was able to diagnose the performance without detachment.
Desired and Ripple Effects
1. Stable production of electrical power anytime.
2. The maintenance cost reduction by deletion of unnecessary detachments
3. Enhanced maintenance environment by self-test
4. Steadiness evaluation and accomplishment of plant maintenance reliability
