A Substation Monitoring System can help a utility monitor equipment and other elements in a substation. The costs of a system are determined by its features and complexity. These factors should be weighed against the costs of installing one. For example, standalone systems can be costly to install, and require a dedicated communications network and software infrastructure. Moreover, they require ongoing installation and maintenance, making them unsuitable for small distribution substations.
There are two primary types of Substation Monitoring System, wireless and wired. Wired systems are used in remote locations and can degrade with changing environmental conditions. Wireless solutions have several advantages over wired ones. They require less maintenance and are easier to implement. An electrical equipment condition monitoring system calculates information from sensors deployed in the field and uses this information to predict the need for maintenance. Different types of sensors are used for this purpose, including potential transformers, current transformers, resistance temperature devices, moisture sensors, position sensors, and so on. Data collectors, such as industrial computers or programmable logic controllers, collect data from these sensors. Once this information is processed, it is then sent to the central data concentrator unit. To maintain a safe and reliable power distribution system, it is crucial to regularly monitor transmission lines and electrical substation equipment. Regular monitoring and inspection can help ensure proper functioning of these equipment’s. Simplicity and scalability are the main factors in determining the proper structure of a Substation Monitoring System. The main challenges when designing a system to monitor substations have always been the communication. Not every substation is the same size or importance, and many are located in remote locations. Therefore, there are some key components to consider while designing a system. An effective video monitoring system must communicate with the SCADA system in the control center. It should generate alarms, and alert the operator to investigate. A video system will require a small amount of bandwidth. It can use a common communication path for video data to avoid overwhelming the existing connection. It will also allow operators to remotely monitor video streams. In addition, video analytics can detect problems at remote substations and send alerts to operators. The installation, implementation, and maintenance of Substation Monitoring System can be very expensive. Depending on the number and type of sensors, SMS can be expensive. A system that is compatible with all types of devices and equipment will have a low total cost of ownership. However, if you have multiple substations with varying voltage levels and sizes, SMS may be a good choice. SMS is an inexpensive and efficient solution for a substation communications infrastructure. Early digital technologies were limited in number of data points. The slow data exchange rate and high cost of communication made the collection of large volumes of data from substations impractical. The applications of Substation Monitoring System are becoming increasingly important. These systems use numerous tools and techniques to monitor electrical substations. Designers can effectively transfer customer requirements to the products, resulting in improved quality using this methodology. A proper monitoring system is essential for a utility's core infrastructure. A good monitoring system must be able to protect the substation and the power grid from downtime. It must also be able to prevent unauthorized changes or upgrades, since utilities are natural monopolies and are subject to numerous regulatory bodies and government agencies. Failure to meet these regulations could result in fines that can run into the millions of dollars.
