3 of 10 INTRODUCTION The Power System Simulator must be a digital system able to perform electromagnetic transient simulations continuously in real time (frequency range DC to ~3kHz). Since one of the main purposes of the simulator will be to test physical controllers and protection devices, it must be equipped with sufficient analogue and digital input and output facilities as well as high level communication capabilities (e.g. IEC 61850 and DNP). In addition to testing protective relays and control devices, the simulator will also be used for general power system studies and power system training. 1 HARDWARE The simulator must be modular in design to allow future expansion of the system. The basic module of the simulator must perform three functions: 1) Computation (i.e. solution) of the power and control system algorithms 2) Ethernet communication to allow control of the simulator via a standard computer workstation 3) Dedicated, high speed communication to allow expansion of the simulator using additional modules 1.1 Computational Units The power and control system computation within each module shall be performed by RISC processors housed on multiple printed circuit cards. The processor cards shall not be dedicated to simulating specific models and the function of each processor contained in a module shall be completely defined by software. The RISC processors used for the simulation solution shall be minimum 64-bit and a clock speed to 1 GHz. To prevent adverse effects caused by communication restrictions, it shall be possible to connect high accuracy, 16-bit digital to analogue and analogue to digital converters, plus digital input and output, directly to the computational units. 1.2 Ethernet Communication The basic simulator module shall have ability to connect directly to a 10/100BaseT Ethernet Local Area Network (LAN) so that it can be accessed by remotely by a large group of users.
