Recently, the Lahore converter station of Pakistan's modiyari Lahore ± 660kV DC transmission project ushered in a major project node on the eve of national day. Reporters from the head office visited Lahore converter station.
Wang Bo, deputy general manager of the third business unit of State Grid CLP Equipment Co., Ltd., who is responsible for the construction work, said that after 22 months of construction, the project has fully entered the stage of live commissioning, and Pakistan power grid has started to have Chinese elements. Lahore converter station is also a project with independent intellectual property rights and independent technology in China. The first ± 660kV DC transmission project carried out overseas will play an important role in the transmission of power from south to North in Pakistan.
The live commissioning of Lahore converter station is the first step of starting the whole system commissioning of the project, which marks the completion of the electrical installation of the converter station and the formal transition from the construction and installation stage to the system commissioning stage.
Since the outbreak of novel coronavirus pneumonia in Pakistan, the material delivery, personnel dispatching and construction progress have been greatly affected. Under the difficulties overcome, the project has been successfully pushed forward, and the first step in success has not been easy.
The merra DC transmission project starts from mertiari in the South and ends in Lahore in the north, with a total length of 890 km. It is developed and constructed by China electric equipment company, a wholly-owned subsidiary of State Grid Corporation of China, with a total investment of US $1.658 billion.
The project was started on December 1, 2018, with a total construction period of 27 months. It is the only power transmission project in China Pakistan Economic Corridor. It is also the project with the highest voltage level and the longest transmission line in Pakistan. After completion, it will become the energy "artery" of Pakistan, sending the energy produced under the southern China Pakistan Economic Corridor to Punjab province, a big economic province.
