Busbar is an important component of power plant and substation. When there is busbar failure of power plant or substation, if the fault is not removed in time, it may cause damage to many power equipment, affect the stability of power system, and cause power outage in substation. In severe circumstance, it may even cause collapse of the regional power system.Busbar protection is an important secondary system device to ensure safe and stable operation of the power grid, and its safety, reliability, sensitivity and fast response are of decisive significance to guarantee the safety of entire regional power grid. Therefore, it is very necessary to set up a busbar protection with safe operation, reliable action and good performance, so that the fault of busbar can be quickly detected and removed in a timely and selective manner.The BP microcomputer busbar protection independently developed by CYG SUNRI was introduced 1995.

With the continuous increase of fossil energy consumption and the deterioration of ecological environment, various countries are actively looking for a new energy source sustainable and non-polluting to the ecological environment. Among them, solar energy, as an efficient and pollution-free new energy source, has become an important part of today`s energy structure.In recent years, the energy storage industry has experienced fast development, the installed capacity of energy storage has also increased continuously, and the market demand is huge. Under this background, CYG SUNRI focuses on the development and production of new energy household energy storage systems, and is committed to providing world-class household storage system solutions, including hybrid inverter, battery management system (BMS) and energy storage system (EMS).

The PRS-3000 energy storage monitoring and energy management system is a cross-platform integrated energy management system introduced by CYG SUNRI, which can realize real-time monitoring, diagnosis and early warning, panoramic analysis, and advanced control functions. This system can satisfy the requirement of comprehensive monitoring of power grid operation, intelligent security analysis, adjustment and control in advance, and dynamic panorama analysis, and ensure the safe, reliable and stable operation of power grid.The PRS-3000 energy storage monitoring and energy management system adopts service-oriented software architecture, follows the IEC 61970/IEC 61968 standard, and has good openness, which can well meet the continuous development requirement of system integration and applications. 

The PRS-3351 intelligent feeder terminal independently developed by CYG SUNRI can provide the functions of fault detection, information upload, control command acceptance and execution. In addition to remote metering, remote signaling and remote control and line loss management, it also supports various FA methods and other distribution line state perception and edge processing function such as intelligent distributed feeder automation. The system can achieve power collection and control, fault detection, fault area location, isolation and power recovery in non-fault area, which can improve the reliability of power supply.
