Static Var Compensator 
Posted by Xi’an Senbao Electric Engineering Co.,Ltd  [Silver] on 05/11/2009
The SVC is made up of controllable reactance, passive filters (FC), and control and protection unit. At present, terms of the principle on which the reactance is adjusted, static var compensators are classified into three types: thyristor-controlled transformer (TCR), thyristor-controlled reactor (TCR), magnetic-controlled reactor (MCR). For their working principle and difference, see “SVC Operating Principle
SENBAO has developed all the three types of static var compensator and launched them on the market successfully. As the only manufacturer in China possessing proprietary intellectual property right of the three types of SVC, SENBAO offers the best performance-to-cost SVC solutions and complete set of equipment to fulfill user requirements.

Step Voltage Regulating Var Compensator 
Posted by Xi’an Senbao Electric Engineering Co.,Ltd  [Silver] on 05/11/2009
As a upgrade var compensator for substations, the SVQR has remarkable advanteges in many aspects such as var compensation precision,, response speed, stabilization of system voltage, reduction of line losses, and enhancement of transmission capacity.
SENBAO developed, for the first time in China, the substation var compensator, SVQR, whose output is changed by regulating voltage across the capacitor. The SVQR has found wide applications in substations. With complete HV and LV testing beds and the-state-of-the-art DSP-based control system development system, SENBAO has gathered a large army of excellent professionls and has passed the national ISO 9001 quality system certification.
The SVQR is widely applied not only for new substations, but also for upgrading of existing substations, transforming the existing manual 1-step TBB into an automatic 9-step voltage-regulating-type var compensator. SENBAO SVQR has been operating successfully at an altude of 4,000 meters in the cold area of Shangri-La, Yunnan, way ahead of the domestic manufacturers of the like products.

SVR Automatic Feeder Voltage Regulator 
Posted by Xi’an Senbao Electric Engineering Co.,Ltd  [Silver] on 05/11/2009
SVR automatic feeder voltage regulator is tracking the variation in feeder voltage and changing the turn ratio of the built-in transformer, thus maintaining its output voltage within the permissible range. SVR functions satisfactorily when its input voltage fluctuates within 30% of its rating, ideal for feeder lines with large voltage drops and/or voltage fluctuations. Installed at the medium or receiving end of a feeder, SVR can effectively keep the user voltage at desired level and reduce power loss over the line. Moreover, SVR can also be applied to substations without on-load tap-changer transformers. Installed at the outgoing-line-side in such substations, SVR maintains the outlet bus voltage at specified values.
SVR has been patented for its originality (Patent NO 02 2 92527.9) and received certificates as follows:
 Apr 2004, State Torch Program Project
 Dec 2004, Patent of Utility Model issued by State Intellectual Property Office(SIPO)
 Apr 2004, State Strongly Recommended Product
 2005 Xi’an Priority Technology Industrialization Product
 State Power Grid Corporation Strongly Recommended “Four New Product” for rural power networks

DWK Outdoor High-voltage Var Compensator 
Posted by Xi’an Senbao Electric Engineering Co.,Ltd  [Silver] on 05/11/2009
The DWK is a new type of pole-mounting high-voltage var (reactive power) compensators. It consists of current transformers, potential transformers, controller, vacuum contactor and shunt capacitors. The DWK features high level automation, small size, light weight, and easy installation. It is mostly applied to 6kV and 10kV distribution lines, switching capacitors automatically on multiple modes such as voltage, time, voltage/time, voltage/var, and power factor. Integrating static and dynamic compensation and multi-step switching has realized more precise reactive power compensation on HV distribution lines, thus greatly raising the power factors in the system and reducing power loss on distribution transformers and lines. The DWK is a powerful instrument for enhancing power delivery efficiency and improving user power quality.
The DWK has been patented for originality, Patent Number: ZL02 2 92526.0

DWLK HV Dynamic Var Compensator and Filter 
Posted by Xi’an Senbao Electric Engineering Co.,Ltd  [Silver] on 05/11/2009
DWLK high voltage dynamic var compensating and filtering device when a feeder lines is supplying power to a nonlinear load device, harmonics will be generated and flow in the distribution system. Under such situations, using the conventional var compensators may cause the harmonic current and total harmonic distortion (THD) to increase further, threatening safety operation of the distribution system.
To solve this problem, SENBAO has developed DWLK var compensating and filtering device based on its DWK var compensators. The DWLK not only inherited all the functions and merits, but also can switch in series reactors of proper value corresponding to the orders and magnitudes of the harmonics existing in the var compensating circuit, performing harmonic suppression and var compensation simultaneously and thus greatly improving the operation and power quality of the distribution system.
The DWLK has been patented, Patent No.: ZL2006 2 0135996.8

TAL High Voltage Passive Filter 
Posted by Xi’an Senbao Electric Engineering Co.,Ltd  [Silver] on 05/11/2009
The TAL high voltage passive filters are made up of filtering capacitors, filtering reactors, discharge coils, disconnect switches, and lightning arresters, and mostly used in electric systems at 6, 10, 27.5, 35, and 110kV. Connected to the electric grid through a circuit breaker, the complete filtering set is able to supply fundamental frequncy reactive power to increase power factor, and is also able to refrain curent harmonics from flowing into the system to reduce the harmonic distortion at the common access point. The TAL HV passive filters are especially suitable for relatively stable load such as electrolysis and silicon iron furnaces. However, in combination with thyristor-controlled reactors (TCR), or thyristor-controlled high-impedance transformer (TCT), or magneticall-controlled reactors (MCR), the TAL can perform static var compemsation (SVC) for quickly-changing load such as rolling mills and hoisting equipment.

TSF Low Voltage Harmonic Filter 
Posted by Xi’an Senbao Electric Engineering Co.,Ltd  [Silver] on 05/11/2009
The TSF low voltage harmonic filter is widely used for eliminating 3rd, 5th, 7th, 11th, 13th, and higher-order harmonics in 0.4kV, 0.66kV and 0.9kV electric distribution systems. Depending on the magnitude of the load harmonics and reactive power, the TSF can be automatically put into or taken out of service by a thyristor switch, thus realizing dynamic harmonic elimination and dynamic var compensation for nonlinear loads. It is especially suitable for for large loads requiring var compensation and, at the same time, generating harmonics, mostly fixed-order harmonics. The TSF is capable of responding quickly and filtering out harmonics substantially. It has complete protections and can work stably and reliably, fuilfilling harmonic elimination requirement of fast-changing loads in industries including electric power, machinery, auto manufacturing, metallurgy, shipbuilding, port and harbour, railway, coal mins, and oil fields.

Bi-directional Step Feeder Voltage Regulator 
Posted by Xi’an Senbao Electric Engineering Co.,Ltd  [Silver] on 05/11/2009
BSVR bi-directional feeder voltage regulator is a derivative of SVR series products. In addition to the SVR functions, BSVR is capable of identifying the direction of load flow, tracking the change in input voltage and thus maintaining the output voltage constant. BSVR is applicable to 6kV, 10kV and 35 kV ring distribution networks or multi-source networks, in particular, suitable for distribution lines in mountain areas with many small hydro-electric power stations. In low water season, BSVR can raise the voltage at the end of the line, thus ensuring user power quality. On the other hand, in high water season when load flow changes frequently, by using appropriate control strategy, BSVR can not only inhibit the voltage at each substation and hydro-power station from rising excessively, but also meet the requirement of small hydro-power stations to deliver more electricity to the grid.

BSVR has been patented for its originality.
