| We are dealing with various topics in the
field of control and system engineering of power plants.
Not only are the dynamics of a boiler, T/G and power plants
our active R&D areas, but also the optimization of control
logic and parameters are our another interesting topics.
We have developed several kinds of simulation codes and
models for thermal and desalination power plants. Those
are still being updated. The other important research topic
is, in nature for us, the NSSS control and protection systems. |
| |
| Objective of research on vibration and noise is not only
to guarantee the reliability of machineries and structures
but also to improve the dynamic performance of those. Furthermore,
the state-of-the-art technology of vibration and noise is
well developed from analysis to diagnosis. Now, we are developing
a VMS for thermal power plants. The anti-vibration and anti-noise
control technologies will be our near future research topics. |
| |
| The life assessment and performance evaluation of aged
power plants is our another important research branch. We
have developed a lot of integrated and reliable computer
codes for the purpose. Based on the lots of experiences,
we can show a way to our customers to extend the life and
improve the performance of their aged plants. |
| |
| Finally, we use several commercial finite element codes
to solve the non-linear structural problems such as contact,
buckling, thermo-elasto-plastic with phase transformation,
plastic forming processes and so on. Some special purpose
routines including pre- and post processing are developed
to improve the accuracy and efficiency. Dynamic behavior
and safety analysis of the structures under earthquakes
is also intensively investigated, particularly for the nuclear
power plants. For the reliability and verification of the
solutions, all kinds of possible test and field data are
adopted. We still try to improve the accuracy of our solutions
and techniques. |
