China's Qingyuan Pumped Storage Power Station Starts Operation with Pump-Turbines and Generator-Motors Manufactured by Toshiba Hydro Power (Hangzhou) Co., Ltd.

30 Aug, 2016

GUANGDONG, CHINA— Toshiba Corporation (TOKYO: 6502) today announced that Toshiba Hydro Power (Hangzhou) Co., Ltd. (THPC), its Chinese subsidiary for the manufacture, sales and maintenance of hydroelectric equipment, has completed the supply and commissioning tests of the equipment for the Qingyuan Pumped Storage Power Station in China, which started commercial operation of the last unit on August 20.

Qingyuan, in Qinjyuan City  of Southern China’s Guangdong Province in China, is a 1,280MW plant. THPC manufactured and supplied the four sets of pump-turbines and generator-motors installed in the plant, and also supplied various auxiliary systems and equipment including supervisory control systems. Delivery and installation of the fourth set started in 2013, and was completed in June 2016. The new plant is owned by CSG Power Generation Company, a group company of China Southern Power Grid Co., Ltd. and a ceremony to mark its successful start of commercial operation was held today.

Commenting on the delivery, Takao Konishi, Vice President of the Thermal & Hydro Power Systems & Services Div. in Toshiba's Energy Systems & Solutions Company said, “I am delighted that we have successfully completed this advanced pumped storage power station. THPC has cultivated its capabilities to execute difficult large-scale projects. Toshiba and THPC will continue to promote efficient hydroelectric power plant aim to expand sales of our renewable energy business”

The pump-turbines installed in the plant employ splitter runners, a Toshiba-developed world first designed to handle turbulent water flows in pump-turbines. In a splitter runner longer and shorter runner blades are alternately equipped, and there are more blades than in conventional type runners. This restrains turbulence in the  pump-turbine, reducing hydraulic pressure pulsation, and vibration and enhancing turbine reliability.

Since Toshiba established THPC in January 2005, the company has achieved strong growth by supplying approximately 87 hydro turbines and 101 generators, for Chinese and overseas projects. THPC has absorbed the expertise Toshiba has built up through decades of experiences by establishing dedicated team to handle different aspects such as the management of major projects, the design of various subsidiary systems including Control & Supervisory Computer System, and the commissioning tests in the pumped storage plant. These teams are overseen and coordinated by the overall management team.

China's electricity market is experiencing growing demand for base load power demand, driven by strong economic growth, and the country is responding with a comprehensive power plant construction program, including nuclear power plants. The load balancing made possible by pumped storage power plants makes it an important part of the power generation mix, and going forward the government plans to construct approximately 60GW during the five years until 2020 according to China’s 13th Five-Year Plan (2016-2020). Responding to this THPC has invested a total of 170-million RMB (approximately US$25 million) in building up its production capability and facilities since fiscal 2006.

In 1894, Toshiba Group supplied the first Japanese-made 60kW hydroelectric generator to the Keage Power Station, Japan's first commercial hydroelectric power plant. Since then, Toshiba has supplied over 2,000 hydro power generators with over 56,000MW generating capacity around the world. Toshiba’s Energy Systems & Solutions Company supports efforts to secure a stable global power supply with renewable energy solutions, including hydroelectric, geothermal, wind and solar power systems.
