    Wind Energy Consulting Service Overview

    Wind power is the fastest growing source of new electric power generation in the world. The cost of energy from large commercial wind plants in good wind sites is now competitive with that from more conventional sources, and costs are forecast to decline further with future generations of multi-MW turbines.

    Large wind plants are complex dynamic systems, comprised of many individual wind turbines interconnected with the transmission grid through an extensive medium voltage collector network. Auxiliary systems and equipment may be employed for reactive power control and voltage regulation within the network or at the point of interface to the transmission grid. Supervisory control systems monitor and direct the operation of individual turbines and auxiliary equipment in real time.

    EnerNex has extensive experience with wind turbine technology, wind plant design and operating issues, and technical questions associated with transmission grid interconnection and power system operation. Our years of power systems engineering expertise, along with more than a decade of experience working with wind generation technologies and systems, is unparalleled in the industry. We can assist with almost any power system issue relating to electric system planning, design, and operations relating to wind, including:

  • IEC 61850 Testing

    • IEC 61850 Testing

    EnerNex has the largest concentration of IEC 61850 experts in the industry, including four former heads of IEC 61850 software development teams and the original project manager. Our team helped create the standard and continue to participate in its evolution and application.

    IEC 61850 presents an attractive standardization scheme for electric power utilities because it defines a single automation technology for the entire substation and has the potential to cut configuration and upgrade costs across the life cycle of the substation by 75% or more. It is an international standard that is accepted and implemented worldwide by all major vendors of control, protection and monitoring equipment. Utilities implementing the IEC 61850 standard are now laying the groundwork for an enterpriselevel common communication infrastructure for electric power utilities. IEC 61850 has the potential to transform the substation like no other communications standard, through “plug and play” automatic configuration, elimination of dedicated protection wiring and the creation of smart instrumentation transformers. It specifies the requirements, engineering processes, supporting tools, system life-cycle, conformance testing and the quality assurance requirements and maintenance for the entire substation automation system.

    • Smart Grid Collaborative

    Utility investments are usually large. Smart Grid investments are huge and will impact a broad range of stakeholders – and the impact on those stakeholders will be tremendous. The relationship between customers and energy providers will be fundamentally changed. Costs will be certain; however, benefits will be dependent on programs designed for Smart Grid users and customer participation. Customers will have the opportunity to realize significant benefits. Change to the customer-utility relationship brings the potential for confusion, misunderstanding, and risk.

    The greatest risk to utilities and consumers is that the investment will not be realized as beneficial to stakeholders to their fullest extent possible. Regulators will also be faced with a bewildering array of smart grid-related policy decisions – on everything from cost recovery, to rate design, to customer data privacy and security. Left to the traditional adversarial process in which stakeholders operate in silos, smart grid benefits can get delayed or never materialize.
