MHPS and TEPCO Confirm New Thermal Plant Fault Detection Model is Ready

July 16, 2017

Mitsubishi Hitachi Power Systems, Ltd. (MHPS) and TEPCO Fuel & Power Inc., both of Japan, just confirmed the new fault detection model they jointly developed for TEPCO FP's Hitachinaka Thermal Power System in Ibaraki Prefecture, has passed testing. It can now be rolled out further worldwide.

The confirmation follows a basic agreement reached last September to enter a business partnership targeting efficiency enhancement at thermal power plants worldwide. The alliance partners have subsequently taken steps toward creating a joint business in Operation & Maintenance(O&M)solutions for thermal power generation. 

The effectiveness of the advanced fault detection model was confirmed at Hitachinaka Thermal Power Station. Using data from previous cases of equipment malfunction the model was able to detect signs of an impending tube leak, that could potentially cause a plant shutdown, one month before it actually occurred. This success confirmed that application of the jointly developed model can prevent emergency shutdowns and shorten unscheduled shutdown time for dealing with equipment issues, thereby improving the availability of power generating equipment.

Going forward, TEPCO FP and MHPS plan to launch services making use of the new model and verifying, via an IoT (Internet of Things) platform, equipment data monitored at the Pagbilao Power Station operated by TeaM Energy Corporation in the Philippines and other power stations both in Japan and overseas. The two companies plan to mobilize their respective business infrastructures to launch services for coal-fired power plants in Southeast Asia by the end of this fiscal year.

In the coming years, TEPCO FP and MHPS intend to make this initiative available to diverse power providers around the world, as Japan's way of enhancing the asset value of thermal power plants and making positive contributions to reducing use of fossil fuels and carbon dioxide (CO2) emissions.
