Key Features
Take Power System Simulation to the Next Level
Simulates Very Large Power Systems
Using the latest SGI and Intel technologies, HYPERSIM is the most powerful simulator for testing large-scale power systems. Users are able to study complex phenomenon involving interaction between several controls, protection systems, and HVDC transmission and interconnection systems, as well as FACTS, such as power swings, that affect large power systems. 

Extreme Scalability Using Off-the-Shelf Computers

Power systems with thousands of three-phase buses integrated with several HVDC and FACTS systems can be simulated with hundreds of high-end international processors sharing the same memory. Such capability available with off-the-shelf technologies is beyond the reach of competing solutions that use custom-made computer and communication boards.

Automatic Task Distribution From One-Line Diagram Analysis

Rather than requiring manual HYPERSIM automatically analyses the power system topology defined by an intuitive one-line diagram and determines sharing of processing power to ensure optimum resource allocation, minimum inter-communication and overhead latency. This is a key feature facilitating and reducing the time to prepare large integrating tests.

Precise Load Flow Analyser for Automatic System Initialization

HYPERSIM provides a precise load flow module that calculates voltage angle and magnitude for each bus in a power system for specified load and generator real power, and voltage conditions. At which point, the analyser can calculate initial conditions for control systems using these results.

Real-Time Parameter Modifications

This features allows users to easily modify and set the power system and control circuit parameters, even while the simulation is running in real-time or in offline modes.

TestView  - Automatic Test Control

This tool helps program automatic test sequences and thus perform thousands of statistical, random and Monte Carlo tests with no user intervention and for overnight execution.

Online Results Analysis and Worst Case Waveform Selectiont

TestView also includes a powerful library of real-time signal processing functions enabling evaluation of maximum values of transient waveforms, protection relay operating time, and control system dynamic responses. Waveforms corresponding to worst cases can be stored, based on specified criteria for offline analysis.

ScopeView  - Offline and Real-Time Waveform Display and Analysis
ScopeView is used to display signals and waveforms acquired from the simulator and field equipment. It is the ideal tool for engineers who need to perform mathematical calculations, conduct signal processing, and produce reports. It is tightly integrated with the simulators and allows visualization of signals acquired from real-time and offline simulation, while also serving as an analog and digital oscilloscope. Its ease of use lets the user focus on the results, rather than working on complex scripts for viewing data. All operations are done with the mouse and the learning curve is very short.

High-Precision Valve Firing

The advanced interpolation techniques allow users to accurately simulate the valve firing operations occurring between two time-steps and to avoid non-characteristic oscillations in both real-time and offline simulation modes.

Validated Power LCC and MMC Converter Models

HYPERSIM includes thyristor-based LCC HVDC and FACTS models validated against field tests, as well as MMC HVDC system models.

Rich Library of Transmission Line, Transformer, Loads and Arrestor Models

Validated models of all power system components are supplied with the capability to modify parameters while the simulation is running manually or from the test management software. 

I/O Management Server

HYPERSIM provides an I/O server that allows for easy management of connections between the simulator and I/O signals coming from real equipment, such as protection equipment and control systems. This work is done outside of the model, enabling reuse of I/O configurations and calibrations for many projects.

FPGA-Based IO and Simulation System

HYPERSIM will be integrated (2012Q3) with the OP7000 chassis and I/O system, enabling the use of multi-FPGA boards to implement fast power electronics models running with sub-microsecond time steps to reach maximum accuracy. Such a feature is useful in the simulation of very fast voltage source converters installed in micro grids and industrial systems. FPGA models are easily implemented using powerful floating point nodal solvers and pre-configured models.

Open Hardware Platform
The standard hardware platform for the HYPERSIM simulator is the SGI UV super computer equipped with up 2560 cores. The SGI UV computer is available in three different configurations: UV-10, UV- 100 and UV-1000 packs. For example, the UV-10 pack contains up to 40 CPU cores per 4U chassis.
The Hypersim simulator can also be interfaced with several OP7000 (2012Q4) multi-FPGA and I/O systems to provide faster I/O modules and a versatile FPGA simulation platform for electrical models.

Validation Tests of The HYPERSIM Digital Real Time Simulator with a Large AC-DC Network

Abstract - Hydro-Quebec (HQ) had used for many years a very large hybrid simulator for studying various aspects of its power system network. New developments on its network requires to expand and maintain the simulation facilities, and with the development success of HYPERSIM digital simulator, it was decided to use this technology to gradually replace the hybrid simulator. This paper presents the development and validation of this large scale digital simulator for AC and DC power system performance studies. Validation tests are performed with a relatively large AC-DC interconnected network including generators (turbine,A VR),dynamic loads and a full bipole HVDC transmission system. The network is simulated on both HYPERSIM real-time simulator and on the hybrid simulator,it is connected with the real external HVDC controls. Comparison of simulation results obtained with HYPERSIM and with the hybrid simulator are presented. The benefits of precision valve model as well as the effect of the simulation time step will also been discussed.

Adaptive Protection Deployment in Special Protection Schemes for Hydro Quebec's Transmission Grid 

Abstract - Modern power systems are operating nearer to their stability limits, to meet the increased demands from a deregulated market.  To operate closer to these limits, fast discriminatory protection is required to detect and react quickly to changes. Detection of change in system topology is a strategic function for utilities, allowing them to plan their system defense for severe contingencies such as a loss of corridor situation. A new protection device developed in conjunction with Hydro-Québec, its theory, characteristics and application are described.
