47. two phase and three phase short circuits Just like in the Transmission Code 2007 7 a distinction is made in these guidelines between type 1 and type 2 generating plants with regard to their behaviour in the event of network disturbances A type 1 generating unit exists if a synchronous generator is directly only through the generator transformer connected to the network All other plants are type 2 generating units The following conditions shall apply to type 2 generating plants taking the Transmission Code 2007 Section 3 3 13 5 into account e Generating units must not disconnect from the network in the event of voltage drops to 0 Uc of a duration of lt 150 ms e Below the blue line shown in Figure 2 5 1 2 2 there are no requirements saying that generating plants have to remain connected to the network Voltage drops with values above the borderline 1 must not lead to instability or to the disconnection of the generating plant from the network TC2007 3 3 13 5 section 13 extended to asymmetrical voltage drops If the voltage drops at values above the borderline 2 and below the borderline 1 generating units shall pass through the fault without disconnecting from the network Feed in of a short circuit current during that time is to be agreed with the network operator In consultation with the network operator it is permissible 29 to shift the borderline 2 if the generating plant s connection concept requires to do so
