On July 2017, HollySys successfully signed contract for 2 × 1000MW ultra-supercritical secondary reheat large thermal power new project distributed control system (DCS) project with Datang Shandong Dongying.

Datong Dongying Power Plant 2 × 1000MW new project is only 4 km away from Dongying Port, water transport is extremely convenient, at the same time, Dongying power plant on the brink of the Bohai Sea, abundant seawater, the current project using seawater as a power plant cooling water source. The civil works of the project were fully started in June 2016. The first unit was planned to complete the 168-hour trial operation on October 1, 2018. The second unit completed the 168-hour trial operation on December 31, 2018.

The project uses ultra-supercritical, secondary intermediate reheat, the main steam 620℃, the main and auxiliary integration, the whole plant field bus, a key to start, single-axis, six-cylinder six exhaust, ultra-low back pressure and so on.

The whole plant conventional I/O points to 30000 points, more than 6300 bus devices, configure the controller 122 pairs, the system cabinet and bus cabinet 160 surface. It is expected that after the completion of the project, it will become the largest and most efficient large-scale thermal power project in the whole country and the whole world. It is a milestone for any automation company to participate in the construction of the project.
