Grid code compliance function
The computer representation of the excitation system PSS is in accordance with IEEE standard 421.5 2A/2B/2C, with noise injection and test points. Examples of grid codes for fault ride through definitions. ABB provides studies that comply with grid specifications to demonstrate stability in all cases. In addition, ABB provides a variety of service levels: • PSS parameter calculation • Reference step response simulation • Stability simulation of various different network conditions • Specific AVR functions of on-site tuning service to support grid stability Overlapping PF/VAR controller with LVFRT and OVFRT support functions: UNITROL 1000 equipment provides standard functions to force PF/VAR controller, which allows separation of dynamic control of minimum PQ limiter and slow control of PF/VAC setpoint. The control structure will support network descent by stabilizing the network. In addition, the dynamic detection of the FRT will allow the setpoint to be dynamically adjusted to avoid severe reactive power overshoot to the network. IEEE power system stabilizer UNITROL 1010 and UNITROL1020 provide power system stabilizer (PSS) as SW option. PSS is implemented according to IEEE standard 421.5 PSS 2A/2B/2C. The purpose of PSS equipment is to increase the contribution of generator exciter to improving the stability of the highest possible operating range of generator. UNITROL 1000 provides special functions to support the application of reciprocating engines: • Cylinder ignition frequency filter to suppress the natural oscillation of the engine • Common voltage step of multiple machines to test the performance of the whole power plant, multiple machines are connected through a common boost transformer • Integrated injection signal generator, which can run frequency response analysis without any additional equipment
