The grid relay protection fault analysis and setting management simulation system, based on the graphical modeling, through accurate short circuit calculation and intelligent setting, and by virtue of computer simulation technology, simulates all kinds of faults in power system, analyses various protection coordination relationships and realizes multi-dimensional and multi-index data analysis and calculation to provide a correct and reasonable setting value for running relay protection. The systematical and professional analysis and calculation will help the power system relay protection setting personnel to develop scientific and reasonable relay protection setting scheme, and further to guarantee the safe, reliable, stable transmission and distribution of electric energy.

With the economy development, the scale of power plants, large factories and mining enterprises is expanding day by day, the number of equipment is increasing, the connection mode and operation mode are becoming more and more complex, so the relay protection setting work is also becoming heavier and heavier. The intelligent and digital relay protection setting value calculation in factories and mines are the future development trend of relay protection. Zhongheng JoinBright industrial setting value calculation software, based on the graphical modeling and through accurate short circuit calculation and intelligent setting, realizes automatic setting value calculation for the power plants and factories. The setting value calculation software not only helps relay protection setting value calculation but makes the relay protection personnel released from heavy manual calculation, and greatly improves the work efficiency and accuracy.

Software version:

Relay Protection Setting Value Management System (V2.0)

Relay Protection Fault Analysis setting and Simulation System (BJBR/FZZDDQ)

Power Plant Relay Protection Data Management System(V5.0.1)

With the rapid development of power grid, the workload of checking, issuing and executing of new setting value ticket for relay protection becomes heavier and heavier, and the total quantity of relay protection setting value tickets also increases sharply, which brings a lot of work and inconvenience to the execution, archiving and query of setting value ticket.
       Based on the model object design, the relay protection setting value ticket transfer system deploys B/S structure and can cover dispatching organizations and substations at all levels. The system has the features as practicality, easy operation and convenient management, and realizes the paperless preparation, transfer, release, execution, archiving and query of protection setting value ticket through the Internet as well as improves the management level of relay protection setting value ticket by means of network and information.

 With the rapid development of power grid, a large number of UHV power grid, power grid infrastructure and power grid renovation projects have been built and put into operation, of which the scale is large and the structure is increasingly complex. The stable operation of power grid is facing severe challenges, and the limitations of the traditional relay protection working mode as "pre-setting, real-time operation and regular check" are also becoming increasingly emerging.

 The setting value online check system, launched by Zhongheng JoinBright and based on electric power dispatching system foundation platform, is a relay protection setting value online check system which integrates relay protection setting value online verification, online early warning, online check, online setting and supportive decision-making. Also, it realizes the relay protection setting value adaptive real-time online monitoring, which greatly improves the validity and safety of the actual operation setting value for relay protection device.

After the system reform of the electric power industry and the separation of power plant from power grid, due to the importance and professionalism of relay protection setting value, the setting value calculation service in the field of power generation and power consumption has gradually become a market product with strong demand. Zhongheng JoinBright adapted to the market demand, made use of its own advantages and launched setting value calculation service products. According to the setting value calculation procedures and field data, through short circuit current calculation, setting value calculation and sensitivity calculation, and in combination with the user configured protection device, a set of complete and reasonable setting values are issued. The setting value meets the four requirements with regard to the relay protection and the stability requirements of regional power grid, and provides customers with perfect verification analysis report, relay protection setting value calculation book and relay protection setting ticket.
