Canada China Electric Power Consultants, a consortium of which Teshmont is a member, were retained to carry out studies to determine the optimal generation and transmission expansion sequences to year 2020 for the South China region consisting of the Provinces of Guangdong, Guangxi, Yunnan and Guizhou and for the Province of Sichuan. The work also included the training of Chinese personnel, establishing an overall energy management system and assessing methods of improving the cycling capability of thermal generators manufactured in China. The Chinese Agency was the Electric Power Planning and Engineering Institute (EPPEI), and the Canadian International Development Agency (CIDA)
provided funding.

Transmission alternatives included 500 kV ac and higher voltages, series compensated lines, static var compensators for voltage control, and integrated dc systems. Means of enhancing system stability include use of power system stabilizers at large generating plants, single pole reclosing and generation tripping during heavy load conditions. Detailed studies and cost estimates were carried out to define the preferred transmission configuration. 		 
 
   

Services provided by Teshmont comprise transmission system least cost expansion planning for a 20-year horizon as follows:

  • Project Management

  • The system simulation and analysis computer software and
    hardware utilized in South China were assessed and
    recommendations made as to the appropriate system to meet the
    specific needs

  • The BPA suite of system analysis programs was provided and installed by Teshmont at the Design Institute in each province

  • Transfer of technology by training in Canada and China for technical staff with regard to modern planning techniques

  • Transmission development options were identified based upon the generation expansion plan and load forecast. The performance of each was studied in accordance with specific design and operating
    criteria developed for the system. Studies were performed on a counterpart basis with the Chinese engineers.

  • The preferred option was then studied at a more detailed level with the substation single line diagrams, layout equipment ratings and performance defined, and detailed cost estimates prepared.
