Microprocessors are proving themselves in several advanced electrical power generating system control applications. Their success in handling complex EPGS requirements add credibility to the decision to select microprocessors over discrete logic. To implement microprocessors in a control unit design, a structured design approach is used. This approach divides the effort into the following major steps: requirements analysis, specification, architectural design, detail design, implementation, and maintenance. Hardware and software functions are broken down into single action, highly independent functional blocks. Standardization and consistency in the design of these blocks is stressed. The net result is the creation of reusable functional blocks that can be used in multiple applications. Duplication, in turn, results in improved reliability, reduced testing, and an overall increase in design efficiency. Inherent to the microprocessor are the advantages of complex logic and timing capabilities and flexibility. In the control units, the extensive BIT coverage, control and protection schemes, and ease of function modification illustrate these advantages. As the complexity increases, the nonrecurring costs of software development are overshadowed by the recurring costs of producing an equivalent discrete logic alternative.
