Abstract— Rise of new energy era include a strategy to build a state of the art transmission system is evident. The most likely replacement for the conventional AC transmission is HVDC. It is proven technology with many benefits over conventional technology and has a vast array of application like subsea transmission, interconnection of asynchronous AC grid and many more possibilities. Its most likely implementation is for transmission of long distance bulk power with great efficiency. In this paper we have provided a simulation in matlab of HVDC transmission system based on 12 pulse inverter and rectifier with their controller.
Keywords— HVDC transmission simulation, twelve pulse rectifier and inverter, Matlab simulation.
I. INTRODUCTION
The first implementation HVDC transmission was done in 1954 at Gotland, Sweden. With the success of this a contract for Eel river DC link was established in Canada. It was the first application of solid state valves of HVDC transmission. Now a days we are seeing voltages for DC transmission line rising up to 600kv for the distance of 785km in Brazil. The HVDC transmission is the greatest achievement for bulk power transmission for a longer distance with high reliability.
II. MILESTONE ACHIEVED IN HVDC
The first HVDC link with mercury arc valves and HVDC submarine cable was commissioned in 1954 at Gotland. This was the major breakthrough in both cable and converter technologies.
The first HVDC transmission project using silicon controlled rectifier was installed in 1972 at Canadian Eel river which made HVDC developed actively.
In 1979, the first microcontroller based control equipment for HVDC was installed. The rapid development of power electronics technology and microelectronics technology was possible because of the successful development of high power thyristor after 1970, the thyristor converter valve has several benefits over mercury arc valve like less costly, high reliability, less maintenance, and simple construction.
