What is power system protection & it’s purpose?
Power system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults through the isolation of faulted parts from the rest of the electrical network. The objective of a protection scheme is to keep the power system stable by isolating only the components that are under fault, whilst leaving as much of the network as possible still in operation. Thus, protection schemes must apply a very pragmatic and pessimistic approach to clearing system faults. For this reason, the technology and philosophies utilized in protection schemes can often be old and well-established because they must be very reliable.

Every protection system is required to satisfy the following purpose…..

1. Reliability.
2. Selectivity.
3. Fastness of operation.
4. Discrimination.

1. Reliability : Reliability depends upon ,design , manufacture & maintenance of protection component increase it’s reliability.
2.

    The primary goal of preventive maintenance is to avoid the downfalls of equipment failure. This is achieved by preventing failure before it actually happens for which condition based maintenance and planned maintenance could help to accomplish. Preventive maintenance is designed to restore equipment by replacing worn or old components before they actually fail. Preventive maintenance includes a few practices that will prevent the breakdown of certain equipment like partial or complete overhaul of equipment at a specified time and also include oil changes, lubrication, error checking, and frequent checkups. Workers can also use frequent checkups to record the deterioration of…

    There are things you need to consider when deciding on what type of system protection you are going to use. The things you need to consider are reliability, selectivity, speed, simplicity, and economics. Reliability consists of assurance that the protection system that is in place will operate correctly. Selectivity consists of ensuring that the amount of the service area disturbed is kept to a minimum. The speed of the system must minimize the duration of the fault and also minimize the amount of damage that may occur to the system. The use of the minimal amount of equipment to achieve the type of protection you want is also important. This will keep things less complicated and also relates to the last thing to consider in a protection system which is cost. You want the maximum amount of protection but at a minimal cost. All of these factors help build a cost effective and reliable protection system that will protect our infrastructure.…

    The authors focus on giving a brief overview of why traditional security mechanisms for power systems are inadequate and the need for CPS security. They briefly describe the functional areas of the grid: State estimation-need for SE, mathematically modeling it, testing bad measurements. Constructing the network topology based on data from sensors. Electricity markets-describing the need and the association with SE. Control signals sent to automatic devices/equipment in the grid , based on processed data. The work surveyed is mainly about false data injection attacks and defense at different functional stages of the power systems if present and they open discussions . The authors in a broad sense describe only the principle of the works. They discuss limitations that they find in the works that have surveyed and talk about problems and challenges that have not been covered in literature previously. The authors do not provide a specific solution to the security problem , however, they provide general suggestions on what CPS defense mechanisms could focus on.…

    The separation of protection and security is a design choice. Protection is identified as a mechanism, which means that it is a device that changes an input into a desired output. Security is identified as a policy, which is a procedure to guide the decision making process. Security relies on the protective mechanisms along with cryptology techniques.…
