Compact Unitised substations (CUS) are mini electric transformer substations which integrate transformers switchgear and protection schemes in the same section. This makes them suitable in construction of infrastructures within urban areas because they do not occupy much space, are very reliable and easy to install. Here are the primary benefits of CUS for urban areas:
Space Efficiency: CUS are designed to occupy minimal space, which is especially helpful in densely populated urban areas where space is limited and expensive.
Flexible Installation Options: They can be installed in tight spaces such as basements, small building rooms, rooftops, and any other location with small space. This flexibility helps utilities and developers to maximise available space without sacrificing any other factor.
Ease of Installation: CUS units are also fully prefabricated assemblies that can be installed faster than traditional substations in the network. They are pre-wired, pre-tested, and pre-certified so as to warrant minimal need for on-site installation.
Reduced Downtime: CUS units can easily be established and incorporated with the power distribution system and hence the time to start up power is substantially shortened. This is quite useful since power outages may sometimes lead to losses in the economy and disruption of social activities.
Integrated Protection Systems: Some of the protection features available in many of the CUS units are overcurrent, overvoltage, automatic fault. Many CUS units currently possess protection features such as the breaker and the auto fault detection to prevent overloading as well as short circuiting. These built-in safety benefits improve the systems’ dependability and also reduce the probability of outages.
Reliability and Low Maintenance: CUS units are assembled in factory conditions, allowing for maximum quality of work and great reliability. It also prevents on-site assembly problems which are a key determinant of the reliability of the substation.
Minimal Maintenance: In most cases, compact substations incorporate isolated and self-contained systems. This lowers maintenance costs and directs resources to other infrastructure requirements, which is particularly helpful in densely populated areas.
Environmentally Friendly: These devices are designed to reduce noise which can be a major inconvenience in crowded locations. A large number of CUS units are insulated with environmentally safe fluids such as ester-based fluids which are biodegradable and have minimal effects on the environment.
High Efficiency: A major advantage of CUS is that it can be installed close to the load centres, hence reducing the distance of electricity transmission and thereby minimising transmission losses.
Support for Renewable Energy: CUS units can be configured to support distributed energy sources, such as rooftop solar, electric vehicle charging stations, and energy storage. This adaptability helps urban areas meet their sustainability goals and improve energy resilience as renewable energy adoption grows.
Enhanced Resilience: A number of facilities in the urban centres have fluctuating electrical loads throughout the day. CUS units have the flexibility in terms of capacity to address variable and irregular demands while maintaining the overall voltage and operations.
Load Flexibility: CUS devices are connected to smart technology, and this automatically allows utilities to manage loads in real-time. This lets the grid operators meet the needs of the consumers more efficiently and adjust varied demands without destabilising the grid.
Operational Costs: Due to its efficiency in installation, low maintenance requirements and ability to use energy efficiently, CUS can cut down on operational costs. Additionally, the size needed for such storage has decreased exponentially which translates into savings in densely populated locations.
