Statcom Products Introduction (STATCOM Equals SVG) As the next generation product of SVC, STATCOM has superior performance in response speed, stability of voltage level, reducing system loss, increasing transmission capacity and improving transient voltage limit, reducing harmonics and decreasing occupation area etc. Since 2005, RXPE has begun to research and develop STATCOM with high-pressure large-capacity. In 2006, the STATCOM test platformhas been completed successfully using DSP TMS320F2812. In 2007, the first STATCOM used for traction substation in China developed by RXPE. SVG -Application -- Long-distance power transmission - Stabilization of weak system voltage - Reduced transmission loss - Increased transmission capacity, make the existing power grid play maximum efficiency - Increased transient steady limit - Increased damping under small interference - Better voltage control and stability - Less power flunctuation -- Secondary substation in city (66/110kv) -- Hoist, and other heavy load - Cause voltage level drop and voltage fluctuation in the power grid. - Power factor is low. - Transmission device will cause harmful high harmonic. Above problems can be solved perfectly after installation of SVG of RXPE. SVG Operating Principle SVG is the representative of newest technology in var compensation area. SVG is connected in parallel to the grid, similar to a variable var current source. Its var current can change following the vary of load var current rapidly and automatically. Since the response speed of SVG is very fast, it is also called Static Synchronous Compensator, STATCOM for short. SVG’s fundamental configuration is 2-phase or 3-phase self commutated bridge circuits adopting full controlled power electronic semiconductor devices (like IGBT and IGCT). By adjusting the output voltage amplitude and phase angle or direct controlling AC side current, the SVG can absorb or generate var according to the load reactive power or the grid voltage level. SVG Main Specialized Components A. Transformer B. Power unit C. Input reactor D. Control cabinet E. Full digital control system F. NMI integrative workstation SVG-advantages SVG is the most advanced var compensator technologically, which realizes an evolution of reactive power compensation mode based on voltage source converter. Big volume capacitors and reactors are no longer needed. SVG uses HV IGBT or IGCT with high switching frequency to realize reactive power regulation. Therefore, SVG has the following advantages compared with traditional compensation methods: --Faster response speed --Stronger voltage flicker restrain capability --Wide operation range --Low harmonic content --Small volume SVG—Quality Guarantee A Top quality IGBT module for traction --German EUPEC top quality IGBT modules --Super capability of bearing high current and voltage spikes. B Low inductance power capacitor --High rated voltage and current. --Long service life and free maintenance. --Advanced performance at high temperature condition. C Unique cooling design --Advanced heat pipe design with high efficiency heat radiation technology. --Eliminate heat-island effect of HV IGBT thoroughly. D Low Voltage SVG Test Platform The SVG test platform utilizes US TI TMS320F2812 type DSP as key controller to realize the following tests: --Manually generate adjustable capacitive or inductive reactive power. --Automatically compensate reactive power. --Stabilize grid voltage. --Compensate load harmonics. --Compensate load unbalance --Compensate reactive power, harmonics and load unbalance simultaneously. E International Level Components Test Center Advanced components test center Though RXPE uses components mostly purchased from ABB,TI,EUPEC,TOSHIBA,MITSUBISHI.RXPE is still equipped with the components test center which can perfectly detect all of the incoming components F Various Load Types Many kinds of test loads Utilizing RXPE SVC,FC,HV asynchronous motor and HV synchronous motor, reactive power, harmonics, unbalance, impact current and other power quality problems can be simulated easily. Thus, the full power compensation performance of SVG can be realized in workshop. G High & Low Temperature Ageing Center High & low temperature ageing center All key components of RXPE SVG products are subjected to serious high & low temperature ageing test piece by piece, under the control of ISO9001 quality control system. These tests can lay a solid foundation for the quality of the system. H High Temperature Power Unit Ageing Center Power unit ageing center Key energy conversion parts of RXPE SVG products are power units. Their reliability will determine the reliability of the SVG system. So each power unit must be subjected to 24h high temperature ageing test under rated operation condition before delivery. I Professional HV Full Load Test Center-Base of the Quality Guarantee for SVG --National high-tech industrialization demonstration project. --The unique SVG HV full-load test center in China. --Test voltage of 6kV,10kV,27.5kV,35kV,66kV•Test capacity of 10000kVA --72h continuous full-load dynamic operation. (Ex-work test) J Unique Global Remote Realtime Monitor Center Global remote monitor center create an unique service brand Utilizing RXPE global remote data monitor technology, the clients need only a tele-wire or wide band to feed back the SVG operation data and status to RXPE remote monitor center. All clients can obtain maintenances and supports from RXPE full-time service engineers, which ensures the equipment operate stably and reliably.
