Xcel Energy Strengthens the Grid with Advanced SVCs

Static-VAR-Compensators

T&D World – Xcel Energy uses flexible static VAR compensator topology to adapt to changing network conditions in New Mexico for more stability and voltage control.

In 2010, Xcel Energy Inc. was tasked by Southwest Power Pool Inc. (SPP) to build out the transmission system in southeast New Mexico, U.S., because the oil and gas industry in the area had a growing need for electricity. Oil producers were asking to convert from expensive diesel to more affordable electricity for their pumps. The request from SPP consisted of a transmission system expansion of new 115-kV and 345-kV projects in the region. Spending had to be prioritized between 2010 and 2021 because of the sheer scale of the plan needed to successfully implement the request.

Xcel Energy addressed the plan by implementing projects classified as high priority. This plan resulted in initiating 44 new transmission projects, an investment of US$557 million. In 2016, two static VAR compensators (SVCs) — the China Draw and Roadrunner — were built in southeast New Mexico to support SPP’s request.

The Importance of Protection & Controls (P&C) and IEDs

Power-Substation-P&C-IEDs
Protection and Controls (P&C) engineering and design is extremely important in power grid protection and coordination especially with the use of intelligent electronic devices (IEDs). Proper P&C designs and coordination with protective relaying and IEDs is an essential part of electrical power engineering for protecting large expensive power equipment such as: generators, transformers, transmission lines (TLs), power circuit breakers, electrical bus, etc.

The Value of 3D CAD Modeling in Power Substation Design

Substation-Yard-3D-View
3D CAD Modeling and 3D CAD Design enhances the design characteristics in many ways while providing several benefits. Design efficiencies are improved where traditional 2D drawing representations can be easily achieved from a completed 3D design versus manually drawing each 2D representation in CAD. Being able to view equipment, components, and systems in three dimensional space allows almost endless possibilities towards planning, implementation, construction, and manufacturing efforts, which is extremely important in the electric power industry. 3D CAD Design and Modeling is improving and aiding with power substation designs compared with 2D designs ….

Basic of Designing Power Substations

Substation-Bus
Power substations are the most integral part of a power utilities’ electric system. Substations make up the various electric systems – power generation, transmission, and distribution systems. Power substations consist of power transformers, voltage/potential transformers, current transformers, electrical bus, foundations/structures, circuit breakers, switches, outdoor cabinets, control house, fencing, etc.
Many design aspects and processes go into engineering and designing a power substation from the ground up. This discusses the basic steps performed in planning and implementing a new substation.
