Home Essays Power Analysis of Hvdc The AC-side real and reactive power and DC-side power corresponding to the firing angle from 0 to degrees has been calculated and plotted. Furthermore, the power balance between the AC and DC-side of the converter has been explained.
The 12 pulse converter in the system has been designed by connecting two 6-pulse Graetz bridge blocks in series. The two transformers are modeled as one with grounded Wye-Wye connection and the other with grounded Wye-Delta connection. This connection causes a phase shift between the two 6-pulse converters.
However, the current in the two converters remains the same since they are in series. Electrical Network I. It provides a reference case for testing of simulators and digital programs.

Kanata Rao 1,2,3Dept. of EEE, GMRIT, Rajam, Srikakulam, AP, India Abstract A benchmark system provides a good common . II. CIGRE HVDC Benchmark System The first CIGRE HVDC benchmark system shown in fig. 1 was proposed in The system is a mono-polar kV, MW HVDC link with pulse converters on both rectifier and inverter sides, and connected to weak AC systems (short circuit ratio of at a rated.
The system is a mono-polar kV, MW HVDC link with 12 pulse converters on both rectifier and inverter sides, connected to weak ac systems. Damped filters and capacitive reactive compensation are also provided on both sides. The objective of the assignment is to consider only the rectifier station in the system, idealize it and then simulate it using PSCAD for power analysis of both AC and DC sides of the converter.
PSCAD is a powerful simulator for simulating power systems and their controls. It is being used widely in universities and the industry.
The rectifier side has been idealized by neglecting the AC source impedance, assuming ideal transformer and valves fired at equal time intervals and B. Calculations The following equations are used to calculate the base values, for conversion of units between actual quantities and per unit values.
See table I for system base values. References: Periodicals:   M. Szechtman, T. Wess, and C.
