Electrical power is generated as an alternating current (AC). It is also transmitted and distributed as AC and, apart from certain traction and industrial drives and processes, it is consumed as AC. 

In many circumstances, however, it is economically and technically advantageous to introduce direct current (DC) links into the electrical supply system. In particular situations, it may be the only feasible method of power transmission.

 

When two AC systems cannot be synchronized or when the distance by land or cable is too long for stable and/or economic AC transmission, DC transmission is used. at one “converter station” the AC is converted to DC, which is then transmitted to a second converter station, converted back to AC, and fed into another electrical network. In “back-to-back” HVDC schemes the two converter stations are brought under the same roof, reducing the DC transmission length to zero.

HVDC transmission applications fall into four broad categories and any scheme usually involves a combination of two or more of these. the categories are:

i) transmission of bulk power where AC would be uneconomical, impracticable or subject to environmental restrictions.

ii) Interconnection between systems which operate at different frequencies, or between non- synchronized or isolated systems which, although they have the same nominal frequency, cannot be operated reliably in synchronism.

iii) addition of power in feed without significantly increasing the short circuit level of the receiving AC system. 

iv) Improvement of AC system performance by the fast and accurate control of HVDC power.

Join the 2nd HVDC Energy Highways Conference on October 24, 2018 in Mexico City, Mexico. Visit www.amgfirst.com/hvdc2018, email This email address is being protected from spambots. You need JavaScript enabled to view it. or call +1 (310) 622-9159.

HVDC Energy Highways is the premier event for electric utility professionals and contracting, construction, and consulting companies who are interested in senior executive-level insight and solutions for the engineering, construction, operation and maintenance of High Voltage Direct Current power transmission systems. 

 

The program features a packed two days of senior executive engagement, deal-making opportunities, hands-on technology demonstrations, and a half-day master class on emerging HVDC technologies to help Mexico bring new power generation on-stream to service its growing economy. 

The conference will also include presentations by recognized worldwide experts, executive case studies, and interactive discussion session along with an exclusive industrial exposition. The conference will focus on the latest state-of-the-art HVDC technology and lessons learned for building and operating HVDC energy highways successfully in Mexico and the region.  

Mexico City is the capital and most populous city of Mexico, and one of the most important financial centers in the Americas. This provides the perfect environment to foster senior-level interaction with the key decision-makers who you don't typically have direct access to, such as heads of Transmission business, VPs and Directors in charge of Grid Operation, Chief Investment Officers, Country Directors, and heads of Substation Engineering. 

We invite you to join us in Mexico City on October 25, 2018 as we shape the future of HVDC transmission networks in Mexico and Central America.
