Modelling SVC using Switched Shunt
Hello, I'm trying to model a SVC using "Switched Shunt" in both Steady State and Dynamic. The SVC is calculated to be +/- 100MVAR. Accordingly, I adjusted the parameters of Switched Shunt Data Record to be as follow: Bus Number : 202 Control Mode: (2) Continuous Cntrl Voltage Adjustment Method: Nearest Combination Vhi (pu) = 1.05 Vlo (pu) = 0.95 Block 1 steps = 1 , Block (1) Bstep (MVAR) = -100 Block 2 steps = 1 , Block (2) Bstep (MVAR) = 100
These settings work very good in load flow with base case & contingency conditions and in each case the SVC inject or absorb reactive power maintaining the voltage on busbar # 202 = 1 pu.
However, when I modeled the SVC in .dyr file with the following parameters: 202, 'CSSCST', 0, 3000.0, 0.00, 0.00, 2.4, 0.00, 0.00, 100.0, -100.0, 0.50 /
The dynamic does not initialize INITIAL CONDITIONS SUSPECT: I DSTATE(I) STATE(I) MODEL STATE BUS# X-- NAME --X BASKV ID 868 19.548 -10.444 CSSCST K 202 ZOZOCAIRE225 225.00
The -10.444 MVAR is the Initial MVAR (Base Case) in load flow solution.
PLEASE ADVISE WHAT COULD BE THE MISTAKE AND HOW CAN I SOLVE IT.
