Power Synchronization System Introduction
With the development of electronic technology, electronic products are constantly progress and improved to meet the needs of various fields. Clock system is an electronic product, a very wide range of applications in various fields are inseparable from the system clock and high precision, such as electricity, hospitals, research ,, aerospace, weapons, transportation and other fields . The main power clock used as the power industry, power industry from the time regardless of the precision equipment performance or require very high system clock.
Clock power system is mainly used in power industry, and to provide high-precision time signal scheduling mechanism, substations, power plants, production control systems, along with the synchronization status of the monitoring device is granted time device. Clock source power system time synchronization system based upon the use of space-based grant, the foundation granted when supplemented by mode, adopt a Chinese Beidou satellite navigation system based upon space-based grant, the US Global Positioning System -way way GPS supplemented. The power system synchronous time synchronization system using the frequency resources of the existing communication system, to achieve the foundation grant, and the use of NTP, GOOSE, etc. management function for synchronizing the device to be granted a time. The principle of time synchronization system of power system operation and management follow unified management, maintenance of classification, each dispatching agencies, substations, power plants and should be based on user requirements of the principle and the actual situation, responsible for the operation and maintenance of time synchronization system.
Power SYN4505A clock system is mainly used for electricity, the security of the power system, related to the security and stability of the people of electricity, related to the stable operation of all walks of life, the power system time clock synchronization accuracy and time demanding. Power system clock SYN4505A, the output signal has a time synchronization codes IRIG-B, NTP network, PTP timing when the pulse signal, the serial port time message, the network time message, alarm relay, etc., the input signal is GPS, Compass, GLONASS, IRIG- B code, PTP / NTP networks. When the built-in oscillator keep SYN4505A, punctuality accuracy preheating time should not exceed two hours at keep time for 12 hours under a state accuracy than 1us / h. Power clock system SYN4505A receive satellite standard time signal via the antenna, through the switch conversion, the standard time signal to SYN6109 networks clocks, and other equipment at the required timing while the SYN6109 networks clocks to provide an accurate time for the device. DETAILED works as shown:
Electricity to run the system changing, alert all the time, but after the accident, a must in time , if not handled in a timely manner will result in automatic equipment in the system time is not synchronized , such as variable bit off, relay, etc. The time of occurrence and the actual action It does not comply with the order , but can not lead to the analysis and processing of the system development process and the reasons for the accident power. So power system time synchronization system is to measure, control and protect critical foundation and support the security and stability operation.
