Problems solved by technology

[0008] However, in the method using the discriminator module, the discriminator module performs discrimination so that a plurality of MISs can sequentially occupy the bus for data transmission, but a signal for approving the use of the bus is transmitted among the plurality of MISs in a daisy-chain manner, so that, When an intermediate MIS fails or is vacant, there is a limitation that the next MIS may not be able to transmit data
[0009] Even in TDM scheme, data is transmitted in daisy chain, so when one intermediate MIS fails or is vacant, then there is a limitation that the following MIS may not be able to transmit data, since there are many data sent continuously and bypassed case, there is a constraint that there is a high probability of errors occurring during data transmission

Abstract

A data processing device for a high voltage direct current (HVDC) power transmission system, said data processing device comprising: a plurality of measurement interface systems (MIS) for measuring voltage or current in a high voltage direct current (HVDC) power transmission system; a bus that transmits data on the plurality of MISs; and an optical distribution module (ODM) that transmits data transmitted over the bus to the HVDC power transmission system, wherein the plurality of MISs are configured according to the ODM's A data transmission completion signal is used to increment a counter value, and an MIS corresponding to the counter value among the plurality of MISs transmits data to the ODM through the bus.

Description

technical field [0001] The invention relates to a data processing device and method for a high voltage direct current transmission system. Background technique [0002] High-voltage direct current (HVDC) power transmission refers to the conversion of alternating current (AC) power generated by a power station into DC power at the sending station to transmit DC power, and then the DC power is reconverted to AC power at the receiving station to provide AC power. [0003] HVDC power transmission system is applied to submarine cable power transmission, long-distance power transmission with large capacitance, interconnection between AC systems, etc. Also, the HVDC transmission system enables interconnection and asynchronous interconnection of grids with different frequencies. [0004] The power transmission station converts AC power into DC power. That is, since it is very dangerous to transmit AC power using a submarine cable, the transmitting station converts the AC power int...
