Port had high requirements for a robust eHouse construction to withstand strong, cold winds and salt water
Swiss power and automation group ABB has partnered with the Far Eastern Electrotechnical Company (FEEC), to secure power supply for the Siberian Coal Energy Company (SUEK) at its Vanino bulk terminal in Russia.
SUEK has taken delivery of an ABB compact electrical house (eHouse) based on its high-performing UniGear Digital switchgear solution to safeguard production uptime at the coal mining company’s terminal.
The Vanino terminal is located at the gulf of the Pacific Ocean, and it is the key export gateway from Russia to Asia-Pacific markets. Each year between 1.5-2 million tonnes of coal are handled at the port, making it Russia’s second largest coal port on the Pacific.
To guarantee continued operation at the bulk terminal, where coal is loaded onto the ship, SUEK was looking for a secure and reliable power distribution solution to ensure minimised maintenance needs and downtime. As the port operates year-round, and the weather conditions can be harsh, it had high requirements for a robust eHouse construction to withstand strong, cold winds and salt water.
Further, a flexible and compact switchgear solution was sought that would allow fast load changes and remote operation, as the installation was to be located some distance from the control room.
According to ABB, the solution ensures minimised switchgear footprint, as the metering cubicles can be omitted and spare panels can easily be configured for future applications. The UniGear Digital solution is built on the air-insulated medium-voltage switchgear ZS1, sensor technology and Relion protection relays. The design of UniGear Digital is very robust, with fewer components, which significantly decrease the risk of malfunctions.
The digital switchgear utilises current and voltage sensors, which offer higher flexibility for easy load capacity alteration without any downtime, as the only required action is to set new values in the protection relays. Using sensor technology also brings time savings when commissioning and installing the equipment, said ABB.
To ensure fast and reliable communication, the solution uses IEC 61850, the global standard for communication in substations, and generic object oriented substation event (GOOSE) communication between the equipment. IEC 61850 communication is also used for remote monitoring and control of the substation from the main control room.
The eHouse was delivered completely integrated and pre-tested, to ensure reduced energisation and commissioning time on site.
