Background technique

The substation facility is a key part of the entire power supply line, and the stable operation of the substation is crucial to the safety of the power supply system. At this stage, information control requirements are put forward for the maintenance of facilities in substations. It is required to monitor each substation in real time. Therefore, a large number of various types of sensors are used in substations, so that various data can be used centrally. But this also brings follow-up problems: 1. After the sensor collects the signal, it can only remind or alarm, but it cannot act on behalf of the staff to operate the related equipment; 2. The more the number of substations, the greater the number of collections. The slower the speed of data transmission to the monitoring system, the lower the real-time and accuracy. Therefore, how to develop a system that transmits in time and can perform real-time control on the collected data has become an urgent technical problem to be solved.

As shown in Figure 1, an intelligent control system for substation facilities according to the present invention includes a power grid dispatching and monitoring system 5, a power intranet PCM system 4, and the power grid dispatching and monitoring system 5 is a power grid monitoring platform, which monitors the entire circuit operating conditions. The power internal network PCM system 4 is the power dispatching communication network, which is one of the important special communication networks in my country and the most important and important component of the power system communication special network. The power dispatching communication network includes a large-scale communication private network connecting various power supply stations, substations, dispatching centers and other institutions. The mainstream networking scheme uses SDH equipment and PCM equipment to realize optical fiber transmission and 2M access. PCM is used to graft an analog signal (such as voice) onto a 64kbps digital bit stream for transmission. PCM converts continuous analog signals into discrete digital signals. In digital audio, the pulse code development method, namely PCM, is generally used. PCM code is the abbreviation of Pulse Code Modulation, also known as pulse code modulation. It is one of the coding methods of digital communication. The main process of coding is to sample analog signals such as voice and image at regular intervals to make them discretized. The sampling value is rounded and quantized according to the hierarchical unit, and the sampling value is represented by a set of binary codes to represent the amplitude of the sampling pulse. The power grid dispatching and monitoring system 5 is connected to the power intranet PCM system 4 to establish signal and control data transmission between the power intranet PCM system 4 and the power grid dispatching and monitoring system 5 .

The sensing device assembly 1 is composed of a plurality of collectors of different types, which may be a light sensor 11 , a wind sensor 12 and a temperature sensor 13 . The light sensor 11 is used to collect the insolation condition of the substation, so as to prevent the electrical equipment from being damaged due to the high temperature in summer. The wind sensor 12 is used to collect the strong wind situation of the substation to prevent equipment damage caused by the strong wind season. The temperature sensor 13 is used to collect the equipment temperature in the substation. The light sensor 11 , the wind sensor 12 and the temperature sensor 13 are respectively connected to the central control unit 3 , and transmit the collected signals to the central control unit 3 for further judgment processing. The sensing device assembly 1 can also include a humidity sensor 14, a pressure sensor 15 and a magnetic sensor 16. The humidity sensor 14 is used to collect temperature information in the substation, the pressure sensor 15 is used to collect the air pressure in the substation, and the magnetic sensor 16 is used to collect temperature information in the substation.

When the parameters such as temperature and humidity are found to be required to be manually operated on the facilities in the substation, the power grid dispatching monitoring system 5 sends a control command to the sensing device component 1 to open the windows and exhaust system controlled by the sensing device component 1 . When no hidden danger is found in manual supervision, the central control unit 3 determines that the data in the sensing device component 1 reaches the threshold value, then triggers the alarm 22 to give an alarm, and uses the video camera 23 to record the scene situation, and transmits it back to the power grid dispatching monitoring system 5 , and at the same time open the relevant equipment control terminal in the sensing device component 1 to perform preprocessing when necessary.
