Different technical reports<\/strong> Remark:<\/strong> In order to make testing programs for the hydroelectric set working on the isolated network (items 1.9. and 1.11.), I had previously studied as follows: – operating characteristics of particular hydroelectric set (especially the characteristics of the regulation and excitational systems), – system configurations, – substations characteristics, – consumers characteristics, etc. and after that I proposed the best testing methods and lead the tests myself. Both tests have been made succesfully.<\/strong><\/p>\n 2.
