    Intelligent substation auxiliary control system

    2020-03-26


       

       In recent years, the development of smart grid has gradually become the mainstream trend of the development of China's power system industry. Smart Substation is an important part of smart grid. Intelligent substation is an advanced, reliable, integrated, low-carbon and environmental protection intelligent equipment, which can automatically complete the basic functions of information collection, measurement, control, protection, measurement and monitoring, and support the real-time automatic control, intelligent regulation, online analysis and decision-making of power grid according to the needs , collaborative interaction and other advanced functions of the substation. The network, digitalization and automation of intelligent substation management are the inevitable trend of power development requirements. Unattended, comprehensive management and safety management of substation are the only way to power grid modernization.


       Liaoning Daneng Electric Co., Ltd. has independently designed and developed substation remote vision system, substation video and environmental monitoring system, intelligent substation integrated auxiliary monitoring system, which has complete independent intellectual property rights and is widely used in nearly 10000 substations of domestic power grid.



    System topology



    Advantages of the system:

        Through the application of acquisition and transmission technology, the d1616 auxiliary control host of our company can be used to monitor the working environment of some important places and equipment in real time (such as: voltage, current, temperature, humidity, water leakage, water level, harmful gas, oxygen content, wind speed, wind direction, smoke, open fire, etc.); when the working environment is abnormal, it can display and alarm in time, and through communication The information IP network uploads the data to the municipal and provincial dispatching centers.

    This subsystem consists of two parts: equipment terminal and system platform. Equipment terminal mainly includes auxiliary control host and various sensors. The system platform can intuitively display the size or status of the monitored quantity, as well as the real-time value of the monitored quantity or the occurrence of various faults.

     

    Technical characteristics:

    1. Advantages of "communication level" multi service integration

    2. Advantages of centralized monitoring and unified scheduling

    3. Reliability guarantee advantages of the system

    4. Advantages of multi system intelligent linkage control
