The power load management terminal

Views:


One, overview:
TKFK series of electric power load management system is the rapid development of our company complies with the power industry of our country, in order to meet the increasing power user requirement of power quality and the development of. The device is a communication terminal includes signal acquisition, processing, remote communication function in situ, man-machine interface, control output, such as self inspection equipment. Advanced technology, perfect function, flexible extension, is monitoring the user power supply enterprises, improve the use of a new generation of remote monitoring and control device of electric management level. As the terminal of intelligent acquisition executive load control and management system, widely used in substation, the users, and distribution substation. Can communicate using mobile network GPRS/CDMA or other means of communication and power load management station. The terminal supports multiple protocols of electric energy meter data acquisition, the dot matrix liquid crystal display, menu driven, easy for operation. According to the master plan of power index implementation of local power and energy control terminal, can also remote control command directly receiving station to control the user load. The terminal can be electricity parameters, perform load control results and terminal operation of some important information and alarm information actively report or measure report.

Two, characteristics:
CPU uses the Intel 32 bit embedded system, real time processing ability. With no power down the work of RAM and high performance CPU monitor chip. Stable and reliable operation of equipment, not in the case of a loss of power loss of data. The page management technology, and equipped with large capacity FLASH ROM memory, can carry out mass data storage, terminal before receiving the refresh command, whether or not can store the data off.
In full compliance with the China State Grid Corp issued a new "power load management system functional specification" and "general specification of power load management system" to the terminal requirements, fully realize the "power load management system data transmission protocol - 2004". Support DL/T645-1997 multifunctional electric energy meter communication protocol and the variety of domestic appearance meter protocol.
Flexible communication mode: more independent serial bus terminal, it is easy to connect with multiple functional modules, the terminal has better scalability; according to user's different communication conditions flexibly configured communication module (matching different plugins), network communication support GSM/GPRS/CDMA wireless network, has the advantages of fast speed, small working current, robustness interference is strong, which makes the data transmission with high reliability. Support for antenna integration, variable internal, external mode.
Specially equipped with independent power supply module, using the three-phase power supply, the lack of two-phase (three line four line mode) or a phase (phase three wire mode) can normally work.
The terminal uses the high accuracy is not power off the real-time clock module, the clock hour travel time error less than 0.1s.
Terminal with dead loop control function, can set value and control method in remote or local settings of electricity and power.
Terminal excellent EMC performance, pulse volume, remote signal and control input, alarm output by photoelectric isolation, high anti-interference performance, interference can resist pressure spike, strong magnetic field, strong static electricity, lightning surge, and has strong temperature adaptation range, each circuit board module the soft, hardware circuit and a watchdog circuit and reset circuit, the total end of safe and reliable operation and easy maintenance.
The high speed and high precision digital advanced sampling technology, real-time high speed power calculation, especially in the operation condition of load fluctuation, harmonic content under high can still ensure sampling and measurement accuracy of electric energy.
With the function of configuration function, can be in the local / remote modifying device parameters, support online local / remote software upgrading.
Terminal by the communication interface (RS485 interface) directly or through special meter reading module read the smart meter data. Support more than two kinds of electric energy meter communication protocol; increase the support for multiple protocols, can count the communication and a variety of table.
The capability to expand hardware and software, can meet the requirements of future power voltage monitoring requirements.
The time interval control, factory control, business suspension control and current power depreciation control four closed-loop control for power;
Scalable: no power compensation control support.
The monthly electric energy control, power control, energy charge urging alarm three closed-loop control for electric energy;
The terminal has a self checking function is very strong.
To realize the electric / removal, master station remote tripping function;
Sealed design, PVC waterproof and flame retardant materials, wall hanging type structure, compact size, easy to install.
Commissioning means complete, can be used to debug software models of multi test, terminal program to support online upload.
