The government today said that at present there is no proposal to ban the use of Chinese equipment in power projects. "There is no proposal to impose a ban on Chinese equipment in power projects at present," Minister of State for Power K C Venugopal said in a written reply to Lok Sabha. As informed by the Central Electricity Authority (CEA), no specific issues related to the quality of turbine generators from foreign manufacturers have been brought out by the utilities, Venugopal noted. There were some failures with boiler and turbine generators supplied by Chinese manufacturers to power plants in West Bengal.
At the Durgapur Projects Ltd , one unit of 300 MW was installed by China's Dongfang Electric Corp and was under commercial operation since April 2008. Venugopal said that DPL had not faced any problem with the operation of the turbine.
He noted that due to some accidental failure of the control system, there was starvation in turbine bearing lubricating oil system on May 30, 2010, which led to some damage of the turbo-generator rotors. "The damaged portion of the rotors have been repaired and ready for re-commissioning in May 2011," he added.
According to him, two sets of 300 MW units were supplied by Chinese entity DEC were commissioned at Sagardighi Thermal Power Plant of the West Bengal Power Development Corporation in 2008. "Initially, there was failure of LP Turbine blade of Unit 1. Subsequently, it was replaced and now both the units are running well," Venugopal said.
