Product Description
Product Overview
The DAE-D series substation monitoring and control terminal is a monitoring and control product developed specifically for ring main units and small switchgear substations—devices that are increasingly prevalent in modern urban power grids. It features AC sampling, DC telemetry, remote control, remote signaling, waveform recording, clock synchronization, sequence of events recording, multi‑port communication, support for multiple communication protocols, distributed network communication, local or remote online loading or updating of application software, parameter configuration, and remote diagnostic and maintenance capabilities. In addition, it can store large volumes of data, making it a next‑generation monitoring and control terminal device.
The DAE-D series substation measurement and control terminal is equipped with an Ethernet interface, adopts the standard TCP/IP protocol, and supports a communication rate of 10/100 Mbit/s. The device’s internal bus utilizes a CAN fieldbus network to facilitate communication between its various modules. It can work in conjunction with master and substation systems for distribution network automation, enabling the collection and control of electrical energy data for multiple lines, fault detection, fault zone location and isolation, as well as power restoration in non‑faulted areas, thereby enhancing power supply reliability. It is widely applicable to real‑time data acquisition and monitoring of power networks in substations at all levels of the power system, railway power and electrified systems, and other industrial control applications.
Main Features
1. Adopting a structure based on functional modules in accordance with general national standards enhances the device’s insulation performance and anti-interference capability. It can be installed in a distributed manner or grouped into centralized panels, allowing for flexible deployment in a wide range of applications.
2. By employing modern digital electronic technologies such as network communication technology and high‑performance microcontrollers, the device achieves reliable performance and flexible, convenient operation.
3. Powerful network communication capabilities. The device employs the standard TCP/IP protocol with a 100M communication rate. It is equipped with two high‑speed, versatile Ethernet network chips that are used to establish an in‑station communication network featuring mutual redundancy.
4. Abundant communication interfaces. The device features up to four serial ports (with RS485 or RS232 options available) to meet the communication requirements of various applications.
5. A dual CAN-BUS network employing non‑destructive priority arbitration is used as the communication network between modules. The CAN-BUS network operates in a multi‑master mode, allowing any sub‑module to initiate information transmission proactively, thereby ensuring the real‑time performance and reliability of critical event data transmission.
6. The software design adopts the open, real-time, multitasking operating system LinuxRTOS to manage and schedule various tasks such as data acquisition and control. This not only enhances the software’s operational reliability but also provides scalability. The software follows a path toward standardization and reusability.
7. Rigorous anti-interference design and advanced manufacturing processes enhance reliability. The device uses industry‑standard, industrial‑grade components, with chips featuring SO packaging to ensure dependable performance.
8. Maintainability and Scalability Design. At the dispatch center, via remote control channels, software updates and modifications can be performed directly on the master control unit and all measurement and control devices online. Modules communicate via a CAN-BUS bus, and the hardware can be configured with different numbers and types of submodules according to project requirements.
