This report is actually Chapter 17 of the EPRI HVDC Reference Book and describes a variety of simulation tools for high-voltage direct current (HVDC) systems. Modeling and simulation of HVDC systems is essential in the planning, engineering, designing, and operating stages of an HVDC system.
When existing or new transmission facilities are evaluated, DC transmission may need to be studied in order to determine the most suitable option or prepare a technical specification for the equipment needed. As part of these studies, good modeling of the power system and transmission options is essential.
- To describe the types of simulation tools that can be applied for the study and analysis of HVDC systems and their expected or required performance in electric power systems
- To identify the data requirements for various simulation types
As part of this project, a comprehensive analysis of different types of studies was performed. These studies included pre-feasibility, feasibility, and planning studies; system impact studies and new facility requirements; technical specification preparation; design and hardware testing; commissioning HVDC links; and system performance analysis. Validation of simulation models was also explored.
This report documents types of HVDC system simulations: steady-state, transient stability, dynamic stability, small signal stability, electromagnetic transients, short-circuit simulation, and real-time simulation. It also identifies the data requirements for various types of simulations.
Modeling and simulation provide a way to visualize the impact of an HVDC transmission system on the electric power system. System facilities that are carefully designed will result in effective performance that meets most or all of the anticipated challenges of operation.
EPRI is preparing a comprehensive reference book to address many aspects of HVDC technology. This report represents 1 of 24 total chapters that are planned for inclusion in that book; for example, Chapter 15 (describing overhead lines) is being prepared as EPRI report 1013858. Other chapters will be developed in the future, and a final comprehensive Reference Book will be issued.
The project described in this report is being conducted under EPRI's HVDC Program. Related reports include Life Extension Guidelines of Existing HVDC Systems (1013976), Advanced HVDC Systems at +/-800 kV and Above (1013857), and DC Capability of AC Transmission Lines (1013979).
