摘要

According to a mid-1990's EPRI study, approximately 70% of the power utilized in the United States will be non-linear. Also, it would be safe to estimate that 50% of all electrical devices now contain some form of digital control or computer. Non-linear devices like switching power supplies, uninterruptible power supplies (U.P.S.'s), adjustable speed drives, and solid state ballasts are power conversion devices that utilize power electronic switches to convert supplied AC voltage to DC (and often return it to a controlled AC) for specialized use. Computer controlled electrical equipment like smart switches, lighting, appliances and building control systems and their respective communication and interface networks are connected to the same electrical supply. Such products are relatively new, when compared to the age of the electrical distribution infrastructure that supplies them and the generation and traditional practices that support it. For example, the adjustable speed AC drive for use with AC motors became commercially viable and reliable approximately 15 years ago. Since then, more than 1 million drives have been installed in the United States, however, only 9% of electric motors yet are controlled by a drive, which points towards continued increases in the use of drives. Conversely, electric motors, which are linear devices, have been in existence and operating for 100 years, though they are fundamentally unchanged in their method of operation. The emergence of non-linear devices and computer-based control equipment in dramatic numbers has created new challenges for users and energy providers that are yet, not entirely resolved. The process of interfacing these devices has spawned entirely new market segments, like the area of Power Quality; and new targeted products, like the U.P.S. and power conditioning devices. Perhaps the most important impact of this change is that plant engineers, consulting engineers, facility managers, providers of non-linear and controls products and utility energy engineers now must all become proficient in new areas, and must begin to view their specific area of interest within a broader system. Companies, governments, educators and associations have identified this issue, and are, in some cases, addressing it with new human resource and education strategies, but with limited results. For instance, one provider of industrial products has elected to hire only degreed electrical engineers for it's front-line sales staff. Other companies have developed specialized technical training resources to increase the technical knowledge base of salespeople historically strong in negotiation or promotion. This paper will explore the challenges and opportunities in training and communications in the face of rapid change. It will highlight key attributes of the people and companies involved in the markets of electrical and electronic products and in the delivery and use of electricity to power that equipment. Finally, it will explore methods for quick, but effective education using innovative means.
