Electricity safety is national security
Electricity is the foundation of the national economy. It is related to the development of the national economy and the progress of society. Since the beginning of the twentieth century, due to the rapid development of the national economy, there has been a large shortage of power supply in many parts of the country. With the implementation of China's West-East Power Transmission and national networking, the scale of power networks is expanding, and the development of power security has entered a new stage of historical development. Modern society has higher requirements for the reliability of power supply. The status of power industry safety is more important than ever. Power security and high efficiency have become prominent issues. Power safety has become an important part of national security. The more the economy develops, the greater the impact caused by the power system. The economic and political events that have been caused are not uncommon at home and abroad.
When it comes to power safety production, people often think of no personal injury or death, no major equipment damage accidents, no fire, no large-scale power outages. To achieve this, we have to talk about the relay protection device, which is the control center of power safety. When the power components (such as generators, lines, etc.) in the power system or the power system itself fail, the power system is safely operated. An automated measure and device capable of issuing a warning signal to a running duty person or issuing a trip command directly to the controlled circuit breaker to terminate the development of these events. A complete set of equipment that implements such automated measures is generally referred to as a relay protection device. It can monitor the normal operation of the power system. When the protected power system component fails, the relay protection device of the component should quickly and accurately issue a trip command to the circuit breaker closest to the faulty component, so that the faulty component can be timely from the power. The system is disconnected to minimize damage to the power system components themselves and reduce the impact on the safe power supply of the power system.
This shows the importance of reliable and stable operation of the relay protection device, which is the focus of power maintenance and debugging. The DT6000 can be used to fully test the relay protection device during system joint debugging or single unit debugging.
When the test protection logic function is normal, use the DT6000 to simulate various faults to test the action behavior, action time and action settings of the protection device. Protection Under normal working conditions, the DT6000 applies various status sampling values ​​to the device, and checks whether the corresponding action behavior is correct through the GOOSE receiving function of the DT6000. Use the GOOSE transmission function of the DT6000 to simulate the GOOSE opening of the protection and measurement and control device, check the corresponding opening function of the protection and measurement and control; use the GOOSE receiving function of the DT6000 to view the GOOSE opening of the protection and measurement and control device.
