Medium Voltage PLC Solution Topscomm Medium Voltage PLC System ConstitutionTopscomm medium voltage PLC communication utilizes 6-35kV power line as transmission channel, with many advantages like small investment, simple construction, convenient maintenance, synchronous with power grid construction, fast engineering launch, coverage consistent with power system, etc.Topscomm medium voltage PLC system is composed of carrier host, carrier slave and coupler, widely used in electricity consumption information acquisition field and distribution network automation field. Technical SpecialtiesTopscomm MV power line carrier communication technology is equipped with our own patent technology of low-voltage PLC, and provided with targeted and creative research. With advantages as below: a) Advanced FEC technology to lower transmission data error and improve communication stability; b) Self-developed TCSK modulation-demodulation technology and Active Noise Cancellation to optimize anti-noise performance;c) Self-adaptive impedance matching technology in response to time-varying power line channel ;d) Flexible ad hoc network based on multi-relay strategy to extend the carrier transmission range;e) Network management software with friendly HCI and visual model, which can be used to monitor the real-time communication states remotely;f) Strict experimental testing, including dielectric withstand and lightning surge test to ensure the security and reliability of power grid. Advantages Improve the efficiency of energy production, distribution and save costs. It requires no new deployment or infrastructure for the utilities. They only need to install PLC equipment.Avoid civil works and consequently the associated expenses and delays.Make the information about the status of the distribution network and the available resources in a reasonably fine time resolution, increased the efficiency.Analyze the behavior of different applications running over the MV-PLC network and verifying the capability to detect in advance an infrastructure failure, such as availability, security, time response, integration with Distribution Control Centre Systems, among others.Using existing infrastructure allows a rapid network roll out, and we can provide integrated services with the precepts of our “information society” requirements: reliability, high performance and universal access.Even for high density areas, MV PLC has enough bandwidth for providing broadband services to several hundred users.Avoids dependency on telecommunication operators (incumbent or not).
