What is a network management system

The network management system is a key component that ensures good transmission of power and maintains the balance between power generation and consumption by monitoring and controlling the power grid. They are known in the industry as SCADA, or system control and data acquisition systems, and can be said to be the brain and central nervous system of the power grid. There are advanced technologies and background knowledge behind these systems, which provide important support for the operation and management of the power industry.

The history of power control can be traced back to the 1920s, when ABB created the world's first power plant remote control system. Subsequently, in the 1960s, the emergence of computer process control technology made modern power grid control a reality. The development and application of these technologies have brought tremendous changes and progress to the power industry.

Over the past 40 years, ABB has always been at the forefront of this technology and has launched more network management systems than any other company.

For SCADA systems, meter reading systems can collect information from thousands of data points and feed it back to the computer system for storage and analysis. This process helps national or regional power grid managers obtain accurate data and provides important support for power grid operation and optimization.

Network Management and Energy Efficiency Saving

Network management is an important tool for reducing power loss. It can monitor and control the entire power transmission and distribution network in real time, effectively improving the operating efficiency of the power department.

By collecting data, the power department can conduct grid modeling and power outage simulations to find the safest and most efficient way to operate the grid. By controlling the voltage levels of the grid, they can minimize power losses.

Network management technology can quickly take measures to restore the normal operation of the power grid during a power outage and spread the load in a systematic manner to avoid grid collapse and large-scale power outages. These technologies can also provide users with direct benefits such as increased grid uptime and optimized resource allocation.

ABB's SCADA system is called "Network Manager" and it consists of 14 different software components. These components can be integrated to meet the needs of different customers such as urban distribution companies, national transmission systems, industry and rail sectors, etc. The purpose of the system is to provide comprehensive monitoring and control functions to ensure the stable operation of the power system and provide real-time data and reports to help customers make accurate decisions. Whether in urban environments or industrial fields, ABB's SCADA systems can provide efficient solutions to meet various needs

ABB has installed India’s first urban grid management system, aiming to reduce transmission losses in the country. This system will help India improve the efficiency and reliability of its power grid.
