iMCC ( Intelligent Motor Control Center) control switchboards are low voltage switchboards dedicated to energy distribution, as well as control and protection of motors. They are used in continuous and semi-continuous processes, in which it is necessary to group the motor starters together in one place for operational and maintenance reasons.

Integration of motor starters in iMCC switchboards
iMCC control switchboards make the work of operation and maintenance teams easier by improving the availability of the process, via:
• Control of motor starters using wire-to-wire cabling or via remote I/O located as close as possible to the starters and connected on the network
• Protection of the motors using an intelligent electronic protection relay. This provides more precise protection of the motors (analysis of operating conditions and alarm thresholds before tripping, etc).
These two functions can be grouped together in a single product, the electronic protection module. In this case, the protection relay module manages and transmits all this control and protection information directly.
Advantages of iMCC switchboards
iMCC control switchboards provide a high level of process availability while ensuring the safety of property and personnel. This solution decreases the number of process stoppages and their duration, reduces maintenance, reduces and repairs costs and optimizes process productivity:
• Reduction of process stoppages as a result of detailed alarms and diagnostics that enable staff to react before the motor starter trips, or react more quickly if it does trip
• Rapid diagnostics due to the availability of more detailed information on the stoppage conditions
• Analysis of stoppage logs using statistics from the electronic protection module.
iMCC control switchboards make installations easier to create, by reducing engineering and debugging time:
• Rapid parameter-setting as a result of local or remote downloading
• Analysis of phenomena via alarms, detailed diagnostics and stoppage logs (statistics embedded in the electronic protection module).

iMCC ( Интеллектуальный центр управления электродвигателями) представляет собой низковольтное комплектное устройство (НКУ) распределения электроэнергии, защиты и управления электродвигателями. Такие НКУ используются для управления непрерывными и полунепрерывными технологическими процессами, в которых для обеспечения эффективной эксплуатации и технического обслуживания необходимо, чтобы пускатели были размещены в одном месте.

параллельная система ИБП

[Интент]

Parallel Operation: The system shall have the option to install up to four (4) UPSs in parallel configuration for redundancy or capacity.
1. The parallel UPS system shall be of the same design, voltage, and frequency. UPS modules of different size ratings shall be permitted to be paralleled together for purposes of increased capacity or UPS module redundancy. The UPSs in the parallel configuration shall not be required to have the same load capacity rating.
2. Parallel Capacity: With N+0 system-level redundancy, up to 2MW of load can be supported by the system.
3. Parallel Redundancy: With N+1 system-level redundancy, up to 1.5MW of load can be supported by the system, and only the UPS being replaced must be isolated from the source (bypass operation is not required for the entire system during the UPS replacement procedure).
4. Output control: A load sharing circuit shall be incorporated into the parallel control circuits to ensure that under no-load conditions, no circulating current exists between modules. This feature also allows each UPS to share equal amounts of the total critical load bus. The output voltage, output frequency, output phase angle, and output impedance of each module shall operate in uniformity to ensure correct load sharing. This control function shall not require any additional footprint and shall be an integral function of each UPS. The static bypass switches shall be connected in parallel.
5. Parallel System Controls: To avoid single points of failure, the UPS system shall have no single dedicated control system designed to control the operation of the parallel UPS system. Control of and direction of parallel UPSs shall take place via a master/slave relationship, where the first UPS to receive logic power asserts itself as a master. In the event of a master failure, a slave UPS shall take the role of master and assume the responsibility of the previous master UPS. Regardless of which UPS is master or slave, user changes to the system status, such as request for bypass, can be done from any UPS connected to the bus and all UPS on the bus shall transfer in simultaneously.
6. Communication: Communication between modules shall be connected so that the removal of any single cable shall not jeopardize the integrity of the parallel communication system. Load sharing communications shall be galvanically isolated for purposes of fault tolerance between UPS modules. A UPS module's influence over load sharing shall be inhibited in any mode where the UPS inverter is not supporting its output bus. Transfers to and from bypass can be initiated from any online UPS in the system.
7. Display: Each UPS multi-color LCD touch screen user interface shall be capable of using an active touch screen mimic bus to show the quantity of UPS(s) connected to the critical bus, as well as the general status of each UPS, such as circuit breaker status information. Any touchscreen display shall support the configuration of the [entire parallel] system and shall provide event and alarm data for all UPSs in the parallel configuration. A Virtual Display Application shall be available for download to the customer’s computer and shalll support remote monitoring of a complete system with up to 4 UPSs in parallel.
8. Battery runtime: Each UPS must have its own battery solution. The battery solution for the entire system can be a combination of standard and third-party batteries, but each UPS must use only one battery solution – either standard or third-party batteries.
9. Switchgear: A custom switchgear option shall be required for parallel operation.

The power meter includes one solid-state digital input.

A digital input is used to detect digital signals.

For example, the digital input can be used to determine circuit breaker status, count pulses, or count motor starts.

The digital input can also be associated with an external relay.

You can log digital input transitions as events in the power meter’s on-board alarm log.

[Schneider Electric]

В многофункциональном счетчике имеется  один полупроводниковый двоичный вход.

Он используется для приема двоичных сигналов.

Например, двоичный вход может использоваться для определения положения автоматического выключателя, подсчета импульсов или числа пусков электродвигателя.

Кроме того, двоичный вход можно соединить с контактом внешнего реле.

Изменение состояния двоичного входа можно записывать в журнал аварийных событий многофункционального счетчика электроэнергии.
