1. System introduction
KS6000 substation automation system is a new generation of substation automation system developed by our company after summing up many years of experience in the development of domestic and foreign power automation. The system is based on domestic and foreign industry standards, and platform and modularization are the design direction. Applications The computer software and hardware technology, network communication technology and automatic control principle can meet the requirements of power system and various enterprise users for protection, measurement and control, local monitoring and remote transmission.
The KS6000 system station control layer equipment is based on a distributed, modular design based KSmart monitoring system, which can be configured according to the needs of different users, and can meet a variety of applications from different sizes, from single-machine systems to multi-machine configurations. Complete the functions of local monitoring and five preventions, voltage and reactive power control, and remote data transmission of the substation. The system can provide equipment status monitoring and control, protection information recording and analysis functions, flexible configuration, friendly interface, easy for user operation and management.
The KS6000 system's bay layer equipment is independently configured for primary equipment such as lines, circuit breakers, and buses, and mainly performs protection and measurement and control functions. KSP600 series protection measurement and control device fully considers the impact of the harsh operating environment on site (high temperature, humidity, strong electromagnetic field interference), and can be operated on site for a long time. Each bay device is relatively independent in structure and function. Fast bayonet industrial Ethernet connection is used between different bay devices, and it communicates directly with the station control layer equipment. It eliminates the cables originally used to introduce a large number of signals into the main control room. Communication server improves reliability.

3. System characteristics
Complete web-based solution
The KS6000 system adopts the Ethernet communication method from the bay device, and adopts a high-efficiency balanced communication method regardless of the internal or external communication protocols. The system has high-speed and relatively high-quality information collection, transmission, and response. Advantages of high reliability.
Universal Embedded Platform
The core module of the KS6000 system bay device uses a 32-bit microprocessor, equipped with large-capacity RAM and Flash Memory, and an embedded operating system, which enables the device to have data processing, logical operation and information storage capabilities, and adapts to electricity Evolving industry standards.
High standards of electromagnetic compatibility
The design of the KS6000 system starts from the overall electromagnetic compatibility performance of the product. The design of the spacer device is no longer limited to certain parts that meet certain anti-interference standards, but from the device's AC input, DC power supply, switching input and output, and Communication and other links for electromagnetic compatibility design.
The equipment of the spacer layer of the KS6000 system has passed the tests of 9 items including electromagnetic radiation and transient interference of the national electromagnetic compatibility laboratory. All the test results prove that its electromagnetic compatibility performance index is higher than the national standard, thereby providing the decentralization of the spacer layer equipment. Reliable protection.
Open design thinking
The KS6000 system is based on open design ideas, which improves the interoperability between it and other devices, and reflects the flexible and long-term design ideas of designers. Regardless of whether it is a bay-level device or a substation-level device, under the premise of ensuring its integrity, it emphasizes the interconnection with other smart devices.
In the interface design of the bay equipment, in addition to using the Ethernet communication interface, it also provides compatibility design with existing communication methods, thereby making the design or transformation of the substation monitoring system more flexible.
