For the first project, Emerson is modernizing the controls at the MuJu pumped storage plant, located in MuJu-Gun, Jeonlabuk-Do, south of Seoul, Korea. The two-unit plant, with a maximum installed capacity of 600MW (2 X 300MW), has been in operation since 1991. The fast-track project required equipment delivery within five months of the contract award. Installation will take place during a scheduled two-month outage, with the plant scheduled to resume generating electricity at the end of this month.
Emerson is responsible for engineering, procurement, installation, testing and commissioning of the Ovation system, which will perform data acquisition, as well as monitoring and control of the electrical control system, hydro turbine governor and balance of plant processes. The contract also includes partial discharge monitoring for high voltage motors and generators.
Emerson is supplying eight workstations and seven controllers for the MuJu plant. When it is up and running, the Ovation system will monitor and control a total of 4541 I/O points at the hydroelectric facility. Emerson is also remodelling the facility’s control room, which in addition to controlling operations at MuJu, will also be used to remotely monitor and control operations at the Yecheon facility, located more than 160km away.
For the second project, Emerson will install its Ovation system at the new two-unit Yecheon project in Yecheon Kun Kyungsangbukdo, southeast of Seoul in the Yecheon resort area. Yecheon Unit 1 is slated for commercial operation in September 2011; Yecheon Unit 2 is expected to come online three months later. The 800MW plant (2 X 400MW), will have the largest capacity among existing pumped storage power plants in Korea and will play a major role in stabilizing grid operation at peak times.
At Yecheon PSPP, the Ovation system, which will monitor and control a total of 3720 I/O points, will be responsible for data acquisition, as well as for monitoring and controlling the electrical control system and balance of plant processes. Emerson will also provide partial discharge monitoring for high voltage motors and generators, and Web closed-caption TV. Under the contract, Emerson will provide a total of eight workstations and six controllers.
