Business background:

As an important part of smart grid, smart substation is an important data source for smart dispatch. Whether the dispatching master station can carry out reliable dispatch management on the end of the substation plant is very important, and the remote control is an important measure to solve this problem. In short, the smart substation remote control point refers to the process of collating the substation information stored in the dispatch center with the actual substation information, verifying that the two are consistent, and thereby finding out the wrong information stored in the meter.

Industry Status:

At present, there is very little research on the point-to-point testing of substations at home and abroad, and the manual point-to-point debugging method is usually adopted, that is, the master station staff is dispatched to connect the substation, and the main station table information and the actual information of the substation are manually checked and debugged Some single debugging tools, however, in the actual operation of the power grid, the database information of the substation and the debugging main station are updated frequently, and the workload of point-to-point debugging of automated equipment is very large. Continued use of this method obviously cannot meet the requirements of intelligent substations. The intelligent substation telecontrol automatic point-to-point system is gradually becoming the main trend of point-to-point work because it is based on a computer, realizes point-to-point with minimum manpower and shortest time.

Applications:

Apqi and Chengdu ** Electric Power Technology Co., Ltd., which focus on the research, development, production and sales of electric power test equipment, have achieved automatic point-to-point testing of ** 500kV substations, ** 220kV substations, and ** 500kV substation remote control devices. The hand-held substation intelligent point-to-point device is an intelligent debugging device developed based on the intelligent substation "IEC61850 standard", "DL / T 634.5104 standard", "Substation data communication gateway machine technical specifications", which can realize the offline adjustment of offline information Mechanization, mechanization and record traceability. The remote control information joint debugging work is free from the constraints of manual cooperation and online development, effectively separating the manual and automatic parts of the information point check work, and reducing the debugging cycle and debugging manpower for this work. It can be widely used in all stages of 110kV-750kV intelligent substation debugging, acceptance, operation and maintenance.

system requirement:

In the entire point-to-point device system, the customer has set the following requirements for the security, volume, data collection, and real-time response of the industrial computer:

1. Light weight and easy to carry, the weight of the whole machine is less than 2kg.

2. Support LINUX operating system to ensure the safety of the test device accessing the network in the station.

3. Provide RJ45 / USB / serial port and USB interface, which is convenient for importing point configuration files, SCD project files, and exporting test data and test reports.

4. Industrial-grade design, requiring dustproof and waterproof, rugged and durable, to provide protection for field operations in harsh environments.

Product application import:

Apqi, as an industry intelligent special equipment service provider, combined with the enterprise's software solution requirements and the industrial application characteristics of substation intelligent point-to-point devices, provided it with a handheld hardened tablet PC TPP-101 for application import. This machine has a magnesium-aluminum alloy body, a fanless design, the whole machine meets the IP65 rating, good software compatibility, many software development resources, friendly man-machine interface, and can bring user operation experience. In this project, the products imported by the application mainly reflect the following technical characteristics:

1. Adopt 10.1 "WXGA + TFT LCD industrial-grade LCD screen, high brightness 350 cd / ㎡, full viewing angle, graphic image display delicate, strong sunlight can still display clearly, capacitive multi-touch, operation on the picture is more intuitive and flexible.

2. High-capacity lithium battery provides 6 hours of working time.

3. It integrates various communication modules such as 3G, Bluetooth, Wi-Fi, and RFID, which creates conditions for the establishment of various industrial applications based on communication.

The smart substation telecontrol fast point-to-point system can not only be applied to the standardized testing related to telecontrol communication between the smart substation and the remote dispatching master station, but also comprehensively support the integrated operation of system regulation and control, and is closely related to the safe operation of the power grid.

Apqi handheld ruggedized tablet PC TPP series can meet the hardware requirements of the industry in terms of size, computing performance, durability, security, etc. As a service provider of intelligent special equipment, Apqi is willing to help smart substations can be divided The layer realizes more and more complex automation functions and improves the overall operation level of the power grid.
