Substation Automation Solutions

Rockwill 07/26/2023

Background

Undoubtedly substations are one of the most important parts of electrical energy industry with big number of costly equipment and operations providing smart automation opportunities instead of manual data processing. Fast and accurate reaction to the resulting automated system will guarantee a reliable electricity network as well as maturing analyzed data.

Solution Overview

The smart grid system is a fully automated monitoring and controlling system designed for generation, transmission and distribution substations to precisely track the situation of equipment and unexpected faults. This advanced platform digitizes various manual operations into one resilient structure. It works based on a mature SCADA platform and several subsidiary objects like Industrial Ethernet Switch to fully operate a substation.

Our RWZ-1000 Substation Automation System can perform various functions such as protection, monitoring, communication and control, etc. based on the computer and network technology. It is a dispersed, hierarchical and distributed object-oriented system, in which the IEDs and computers are substituted for lots of devices with single function such as relays, meters, indicators, automation devices and panels. Local Area Network (LAN) is also substituted for plentiful cables. The protection relays in the system are relatively independent to improve the operation reliability substation and reduce the maintenance work. RWZ-1000 system can meet the requirement for substation automation put forward in CIGRE, that is, telecontrol function(telesignal, telemeter, telecontrol, etc.), automatic control function(Voltage and Reactive Power Control, Load-shedding, Static Reactive Power Compensator Control, etc.), metering function, protection relay function, function for protection relay(fault record, fault location, fault line selection), interface function(with microprocessor anti-maloperation, power supply, meters, GPS, etc.), system function(communication with station and local SCADA, etc.).

Key Benefits

Improving substation management process

Facilitation monitoring and protection processes

Maximizing failure prevention by fast and accurate monitoring

Optimizing substation crew' operational performance

Remote accessibility to substations from control center and web application

Design Solution of 24kV Dry Air Insulated Ring Main Unit

Design Solution of 24kV Dry Air Insulated Ring Main Unit

The combination of Solid Insulation Assist + Dry Air Insulation represents the development direction for 24kV RMUs. By balancing insulation requirements with compactness and employing solid auxiliary insulation, insulation tests can be passed without significantly increasing phase-to-phase and phase-to-ground dimensions. Encapsulating the pole column solidifies the insulation for the vacuum interrupter and its connecting conductors.Maintaining the 24kV outgoing busbar phase spacing at 110mm,

Implementation Scheme for Installing Lightning Arresters or Voltage Transformers in Gas-Insulated Ring Main Units

According to insulation type, ring main units (RMUs) can be categorized as gas-insulated or air-insulated. The former installs primary circuit components in a sealed metal enclosure filled with low-pressure gas (primarily SF₆ or mixed gases) as the insulating medium, using cable terminals for incoming and outgoing lines. Due to superior insulation, compact size, and modular design, they are widely used in 10kV outdoor distribution substations and prefabricated transformer stations. However, thei

Ⅰ. Problem ContextAs a core component in urban power distribution networks, ring main units (RMUs) are widely used in residential areas, factories, and public buildings due to their compact structure, low cost, and high reliability. However, internal equipment failures or arc faults may generate high-temperature, high-pressure gas, leading to cabinet explosions that endanger personnel and equipment. While traditional sealed designs maintain insulation integrity, they fail to rapidly release sud
