TEPCO Fuel & Power Inc. and Mitsubishi Hitachi Power Systems Ltd (MHPS) have confirmed the efficacy of an advanced fault detection model they designed for TEPCO FP’s Hitachinaka thermal coal-fired power plant in Ibaraki Prefecture, Japan.

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 plant. 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 plant operated by TeaM Energy Corp. in the Philippines and other power plants both in Japan and overseas. The two companies plan to mobilise their respective business infrastructures to launch services for coal-fired power plants in Southeast Asia by the end of this fiscal year.
