Sistem Solusi Konversi Tenaga

Na gaba da yawan tarihin da ake samu da hanyar, ɗin Rockwill na Power Conversion System (PCS), da yawa daban-daban na battery, yana iya bayar da yawa da yawan abubuwan da aka bukata a cikin smart grid, micro grid da renewable energy.

Akwai nau'in converter/inverter mai sauƙi da yawa da yawan operational modes a cikin PCS na Rockwill wanda ke taimaka da zama mai sauƙi a kan conversion daga DC zuwa AC, tare da harmonic distortion mai yawa, tushen da shiga da kuma yawan flexibility don operashin power system.

Abubuwan

Don haka, PCS, wanda shi ne mafi girma a kan grid da energy storage unit, ana amfani da shi a wuraren da ke bukatar dynamic energy storage, wanda zai iya adana electric power idan an yi hasa a kan grid power, kuma zai iya bayar da shi azaman an yi cuta a kan grid power. Kuma ya kamata a yi amfani da shi don frequency regulation don taimaka wa masu system stability ko kuma zai iya zama main power source ta micro-grid system.

• Accurate and flexible charging & discharging control modes. PCS can realize real-time communication with the Battery Management System (BMS) and accurately monitor the current operation information of batteries. It can control the charging & discharging status of converter and switch conveniently charging & discharging modes among “constant current”, “constant voltage” and “constant power”. Rockwill’s PCS can support multiple types of energy storage elements.

• Free switchover between grid-connected operation mode and isolated grid operation mode. PCS can not only realize bidirectional energy exchange in the grid-connected operation mode, but also can be the main power source in isolated grid operation mode, allowing free switchover between the two modes.

• Soft grid-connected control and electric energy quality control. On the base of the online monitored grid voltage information, the control system can accurately control the output voltage of converter in real-time and can eliminate static and dynamic errors to realize non-impact grid connection. In addition, the control system has online harmonic monitoring function and independent harmonic analysis software module, realizing optimized control of power conversion and ensuring electric energy quality.

• Respond to MEMS commands for peak load shifting. By the MEMS (Micro-grid Energy Management System), it can store electric energy at power consumption valley and release electric energy at power consumption peak, realizing peak load shifting.

• Grid frequency and grid reactive power control. In grid-connected operation, PCS can not only realize primary and secondary grid frequency regulation coordinating with AGC (Automatic Generation Control), but also realize grid static reactive power control coordinating with AVC (Automatic Voltage Control).

• Complete self-check and protection functions. The scope of self-check covers the control system, I/O units, converter power module and so on. Self-check can ensure detecting internal system fault within 1ms, and provide the corresponding operation, such as blocking trigger pulse or tripping. Complete protection functions are provided to ensure the normal operation of PCS.

• Transient fault recording functions. The system can record continuously fault signals for a whole fault period including pre-fault to after-fault. The recorded data file is stored in the sharing directory of the operator workstation, and can be used in fault analysis or accident tracking.
