Function event trees include primarily the engineered safety features of the plant, but other systems provide necessary support functions. For example, electric power system failure amid reduce the effectiveness of the RCS heat-removal function after a transient or small UJ( A. Therefore, EP should be included among the systems that perform this safety function. Siipfiort systems such as component-cooling water and electric power do not perform safety functions directly. However, they significantly contribute to the unavailability of a system or group of systems that perform safety functions. It is necessary, therefore, to identify support systems for each frontline ssstcm and include them in the system analysis.

Electrical power systems are normally three-phase systems connected using wye or delta connections. In wye connections the three phases are connected to form a letter Y with a neutral point at the intersection of the three phases. In delta connections the three phases are connected to form a Greek letter delta (A). Delta systems do not have a neutral hence delta systems are 3-wire systems. A Y connection has a neutral and thus it is a 4-wire system. 

In electric power systems, it is essential to have permanent control of the power in electricity production, transportation, and consumption. Because of speed and reliability requirements, electric power systems were the first large systems to use a variety of automatic control devices for the protection of different parts of the system.

Electric power systems can be thought of as being comprised of three important sectors generation, transmission, and distribution. For most utilities, generation capital equipment costs account for approximately 50 percent of total plant in costs. Generation also accounts for close to 75 percent of total operation and maintenance expense.

An electric power system involves the production and transportation of electrical energy from generating facilities to energy-consuming customers. This is accomplished through a complex network of transmission lines, switching and transformer stations. 

The reliability of a modern electric power system depends on continuous real-time control of power and energy production, transmission line flows, system frequency, and voltage. This complex task will get more involved in the new environment with increased market participation on both the supply and the demand sides. 

The impact of Ice Storm 98 was unprecedented in Canadian electric power system history. The Ontario Hydro Report provides a chronology of the twenty-three major storms that have impacted the system since 1942. The report also provides a detailed inventory of the effects, consequences, and mitigation measures taken due to the ice storm. The estimated direct total cost to Ontario due to the ice storm is 472 inillioii (Canadian), which includes costs incurred by Ontario I lydro, local Ontario and federal governments, the Insurance Bureau of Canada and associated insurance companies, the Department of National Defence, and affected customers, incliidiiig...

The North American electric power transmission system has been described as the largest, most complex machine ever built by humanity. It is a massive network of generating stations, transmission lines, substations, distribution lines, motors, and other electrical loads all interdependently linked for the conversion, transportation, and control of electrical energy. Approximately 60 percent of all energy utilized in the United States passes through the interconnected electric power system. The major goal of the system is to most efficiently and reliably deliver electric power from generating stations to residential, commercial, and industrial consumers. 

One example of the complexity of the process was in load forecasting technology. By the 1960s and 1970s, utilities had developed processes to replicate the extensive electric power system for study purposes to include generation resources, transmission networks and individual points of load seiwice to customers.
