    摘要: A system and method that enable the processing of seismic data. In one embodiment, a system comprises a plurality of processing nodes and a server. The plurality of processing nodes are configured to process seismic data for migration. The server is operatively linked to each of the plurality of processing nodes to enable communication between the server and the processing nodes. The server may manage a set of stored beam tables that can be accessed by the processing nodes in order to process seismic data.

    摘要: This invention disclosed is a comprehensive power quality controller for substation in the electric power system and includes a Thyristor Controlled Reactor (TCR), pure tuned passive filter Zf, additional inductor L active power filter (APF), and a coupling transformer. The Thyristor Controlled Reactor (TCR) provides inductive reactive power and controls the active power filter (APF) as the current source, it is connected with the additional inductor La in parallel via the coupling transformer, then connected to the passive filter Zf in serial to consist a hybrid power filter system, which is connected to the power grid via the circuit breaker or thyristor. The comprehensive filter system provides required capacitive reactive power and filters the harmonic produced by the load and TCR system itself. Because the capacity of the active power filter (APF) is very small which is less than 1% of the harmonic source capacity, so it is a solution with low cost but simple and reliable control mode. It can suppress influence on the passive filter by the “background harmonic” of the substation and prevent the resonance occurred between the passive filter and power grid impedance.

    摘要: The present invention relates to a method and an apparatus for synchronization control of forward link transmitting power during soft handoff, comprising: collecting the current transmitting power TX(i) of the forward links and the current reception quality of the reverse links; selecting the best base station BTS(x), recording and storing TX(x) reported by BTS(x), marking the BTS(x) as the base station with strong reverse link and the others as base stations with weak reverse link; sending the reverse link flags, TX(x) and the number of base stations involved in soft handoff to all base stations; determining whether a base station is the base station with weak link according to the flag from the base station controller; calculating the deviation between the current transmitting power TX(i) and the TX(x) if the base station is with weak link; adjusting the power control parameters and repeating the above steps; the parameters of the reception quality in reverse links are sampled for every frame in the invention, which not only improves the real time performance of synchronization, but also achieves power synchronization of all base stations and improves the system operation efficiency.
