7.1. Identification of dangers in the work of thermal power plants Danger can be defined as a set of conditions that can cause an unwanted event (injury or damage). The danger may be of different kind: natural (floods), technological (structure), sociological (war), and lifestyle (smoking).
In other words, risk is a unit less measure. Table 2 summarizes the operating performance risks for solar PV systems and TEP’s distribution grid. These risks are related to the functionality of the system. Failure events in the performance category typically result in system downtime and will affect the quality and reliability of system operations.
These risks include the grid frequency going out of the ±0.5 Hz limit, feeder circuits disconnecting and shorts to ground. The first two risks are expected to increase as the penetration of solar PV generation increases, because the solar systems may introduce transients or voltages that are out of phase with the grid.
Dejan Lj. Branković 1 Direct research on large and complex systems, such as thermal power plants (TPPs), is generally difficult and sometimes impracticable, especially at the stage of their planning, design, and installation and commissioning.
analysis indicated that the greatest risk for an electric power grid with solar PV systems was weather causing the solar panels to receive less sunlight than expected. This is a crucial factor for a self-sustaining PV system, but it is less important for a large-scale system comprised of both renewable (solar) and non-renewable resources.
