Transmission Management Systems

Transmission owners and operators today face new challenges due to stringent regulatory mandates, system security concerns and inherent capacity limitations in the face of increased transfer demands. Additionally, they are facing growing cost pressures for minimizing or curtailing operational or capital investments in the transmission asset arena. The need for practical, effective and reliable tools to help manage these important assets in real-time has never been stronger.

GMS Platform

Effective management of these assets involves efficient and holistic monitoring of the complex transmission network; intelligent and reliable security analysis tools for developing effective strategies to avert, mitigate and cope with system emergencies; and well-rehearsed scenarios and well-trained operators to deal with localized or system-wide emergencies, blackouts, voltage collapse, loss of critical equipment, etc. The blackout of August 14, 2003, and other similar collapses in various grids in Europe and the Americas, greatly underlined the need for strong and reliable transmission monitoring and management tools as well as effective and realistic operator training systems.

OSI has been at the forefront of developing the next generation of effective Transmission and Energy Management System (EMS) applications since the mid 1990s.

OSI's EMS applications framework was developed from the ground up for effective real-time use, as opposed to the industry's practice of adopting off-line system planning tools. Efficient algorithms, effective on-line maintenance tools, intuitive graphics and user interface techniques provide for a powerful security monitoring and analysis environment for transmission operators.

OSI's Transmission Management and EMS applications have been helping many transmission operators of various size and grid complexity worldwide.

From China's fast-growing and challenging transmission systems to overly burdened transmission systems in Australia, Europe or the Americas, OSI's EMS applications have been the reliable nucleus of many companies' real-time security analysis strategy.

OSI's Operator Training Simulator is the friendliest simulation platform for effective training of system operators. Using detailed dynamic modeling of the power system and an exact replica of the control center environment, system operators can rehearse a full spectrum of system events, emergencies and restoration techniques in the most realistic settings.




Transmission Network Analysis

OpenNet is a high-performance, Network Security Analysis system that is ideal for online security analysis, situational support, operations planning and offline engineering studies. The functionality of OpenNet allows enterprises to transform their decision-making support into a comprehensive, system-based process.


Operator Training Simulator

OpenOTS helps you regain control by giving operators firsthand experience with events ranging from system blackouts to component losses to normal and secure operations. OpenOTS provides simulated real-time system responses to events that let the operators "practice" and "script" their actions without risking the operational integrity of the actual power system.


Common Information Model Interface

OpenCIM provides a platform for the bi-directional transfer of data between monarch systems and CIM-compliant databases or applications using XML data file exchange. Zero additional effort is required to integrate monarch products with existing applications that support CIM standards. CIM XML is the obvious solution for data exchange between different applications.


Transient Stability Analysis

OpenTSA is OSI's real-time Transient Stability Analysis product specifically designed to provide users with accurate and up-to-date transient stability margins based on real-time system conditions and featuring full integration with OSI's various Transmission Network Management applications.


Voltage Stability Analysis

OpenVSA is OSI's real-time Voltage Stability Analysis product specifically designed to provide users with truly accurate and up-to-date voltage stability and reactive reserve information based on real-time system conditions, featuring full integration with OSI's various Transmission Network Management applications.


Automatic Voltage/VAR Control

OpenAVC implements voltage and VAR dispatch strategies that span transmission, sub-transmission and distribution networks. OpenAVC can also manage voltage, VAR and Power Factor levels for individual feeders in a Distribution Network, along with monitoring and controlling branch power factors and bus voltage magnitudes by controlling reactive sources.


Equipment Outage Scheduler

OpenEOS allows you to schedule outages of any power system device including generators, transmission lines, transformers, breakers and switches, loads and reactive compensation devices. With OpenEOS, outage schedules are automatically delivered to network analysis and generation planning functions, minimizing the impact of overlooked system events.


Short Term Load Forecasting

OpenSTLF is a simple and reliable short-term load forecasting tool that relies on neural-network techniques to predict loads with the highest accuracy. OpenSTLF supports multiple load areas or feeders and has the capability to forecast up to 35 days into the future. A feature-rich user interface is supported consisting of various tabular and graphical representations.
