چکیده
Although Electric utility company requires automotive MV distribution system, it is hard to get fine communication network that must be offered with cost effective and reliable performance. MV PLC network has many advantages in aspect of administration, maintenance, easy and rapid installation. Now it is necessary to communicate with DAS (Distribution Automation System) in Korea. So, we design and develop MV PLC System for DAS. This PLC system operates under 400kHz frequency with DCSK modulation(based on Chirp SS) and shows 9.6kbps performance. Also, we investigate ceramic type MV coupling capacitor that has small size and low signal attenuation. We test MV PLC system in real MV field in Korea and show successful communication performance without retransmission in 10 km real field and 18 km test-bed under very high noise environment. This system will be adopted to distribution automation system and AMR(Automatic Meter Reading) In this paper, we introduce the MV PLC system's architecture, technique and experimental characteristics, such as impedance, attenuation and noise of Korea MV system.

Narrowband Power Line Communications (NB-PLCs) are investigated as an alternative option for transferring low rate smart grid (SG) data via Medium Voltage (MV) power lines. In this framework, two variants of orthogonal frequency division multiplexing are examined, namely Filtered-OFDM (F-OFDM) and Wavelet-OFDM (W-OFDM), in an attempt to determine which of them is capable of transmitting low rat...
متن کاملA New Data Rate Adaption Communications Scheme for Code-Shifted differential Chaos Shift Keying Modulation
In a binary Transmitted Reference (TR) system each bit is encoded into two wavelets of finite duration. The information is carried by the sign of correlation measured between the two wavelets. The Code-Shifted Differential Chaos Shift Keying (CS-DCSK) modulation scheme transmits the two wavelets in the same time slot and applies two Walsh code sequences to keep the wavelets separated. The CS-DC...
