The mountains pass in the cloud, the ships fly from the sky

Since SmartGen launched the marine diesel control business, we have been wading into the waters. For a person from the central plains, it is both afraid and excited about water for him(her). Fearing of water is because they are not good at water, and excitement is because they think there is a lot to be done in the vast world.

This case is two ships in a reservoir of the South-to-North Water Diversion Project, using the engine control box of SmartGen HMC9000A , and the engine of ships are certain Swedish brand. The acceleration and deceleration switch signal is converted to 4-20ma signal by HEP300 electronic potentiometer through the accelerator pedal, and the current signal is converted to CAN signal by HMC9000A to ECU, and the engine executes the corresponding actions. One ship is an engineering salvage ship, the other one is a water quality monitoring ship, both of them are electric push ships, using the accelerator pedal to control the speed of the ship.

Your Super Brain——the application of marine HMC9000A and HMC6

You were the focus of the public attention, rising star, peakedness of power. With good appearance and strength, you are always obligatory when power is needed to solve the power problems for mankind all the year around.

However, you became invisible and dusty as time goes by, you were on the road to being traded. After many years, finally someone discerning, found once brilliant you. But you’re in a state of devastation and your old brains can’t keep up with modern technology, so they’re fixing you up to make you innovative and glowing.

The existing conditions of this renovation
The offshore drilling platform of a shipyard is mainly used to provide power support for the vertical composite powerful drilling rig, which is used for bridge piers and wind power base drilling. Two famous brands engine and generator from overseas with the power, speed, frequency and voltage are respectively 1700KW, 1800rpm, 60HZ and 440V. The governor is manual04121 from WOODWARD, the partner of SmartGen, and the digital regulator is DVR2000E from Marathon.

The renovation mode
The single machine control system of the two units is transformed into a control system that can output simultaneously, adopting engine control system of SmartGen HMC9000A and HMC6 power management control system, using the marine control mode to realize muti-units parallel management.

The advantages of this renovation
HMC9000A and HMC6 perform their respective functions. Because the cabin space of a ship is relatively small, the surrounding environment is poor, the engine noise is harsh, the air quality is poor, and the environment is sultry. The HMC9000A control box acts as a guard, guarding the engine as best as it can. When the engine is abnormal, the control system will send an alarm (to judge whether it is alarm or stop), and send it to the distribution room at the same time, and execute the corresponding action. HMP300 power comprehensive protection module is equipped in the control box, which can observe the power generation parameters in real time. HMC6 is used as power management control. The distribution control room has a relatively good environment, and air conditioning can adjust the indoor temperature. HMC6 mainly controls electric parameters to achieve power distribution. HMC6 has manual and semi-automatic operation mode. In the manual mode, it can start the car manually, close the switch manually, operate parallel connection manually, open the switch manually and stop the machine manually. In semi-automatic mode, HMC6 controls the starting, paralell operation, closing, stopping, overpower, inverse phase, overcurrent, overvoltage, undervoltage and other protection of the geneset.

The highlight of this renovation
Three containers are placed separately. Two containers are placed respectively for two units, and the other container is placed for the switchboard, cables and signal wires are used in the middle for fast connection with strong mobility.

Two-line One Bus Tie Solution – HAT821

HAT821 dual power bus tie controller is mostly used in the switching system of two-line and one bus tie. It can detect the voltage and frequency of two lines, judge the normal and abnormal conditions of them, and automatically execute the operation of three circuit breaker switches according to the main setting.

HAT821 advantage 1

Compared with the traditional automatic bus transfer device.
Do not need to separate the manual-automatic button, directly switch between manual and automatic mode on the pannel;
Do not need to lead out multiple closing and opening buttons separately. There are 6 buttons on the controller directly control the closing and opening of the circuit breaker;
Reducing the complex wiring and making operation simpler.

HAT821 advantage 2

Intelligent power supply switch inside the controller.
The circuit breaker switch power supply is normal as long as there is a normal voltage;
Provide AC 220V operating power supply for circuit breaker directly;
L0, N0 power output capacity is 16A, which can ensure the normal power supply for circuit breaker switch.

HAT821 advantage 3

Automatic control function, three kinds of automatic logic are available for users.
(S1,S2 mainly used): both channels are mainly used. When both power supply are normal, the two-line circuit breakers close the power supply respectively, and the bus tie is in the breaking state. When there is one abnormal switch, another switch and bus tie switch close to supply power for two loads;
(S1 mainly used): one channel is maily used, (S1) one channel is normal, one breaker and the bus tie switching the power supply, when one is abnormal and two voltage is nomal, (S2) 2 switches and bus tie switching power supply;
(S2 mainly used): two channels are mainny used, (S2) two channels are nrmal, two breakers and bus tie switching the power supply, when the two channels are normal and one votage is normal; (S1) one breaker and bus tie switching power supply.

HAT821 advantage 4

Multiple communication interfaces.
It has a d-type USB communication interface, which can be used to connect PC to test software configuration parameters and upgrade module programs;
It has two RS485 communication ports, which can not only realize the centralized monitoring “three-remote” function, but also realize the connection with the web of things and realize the cloud monitoring function.

User application cases

Application occasion: the project is applied to a large chemical enterprise.
Application mode: (S1,S2) two main modes in the site. When both power supply are normal, the two-line circuit breakers close the power supply respectively, and the bus tie is in the breaking state. When there is one abnormal switch, another switch and bus tie switch close to supply power for two loads.
Electrical interlock: Two sets of normally closed auxiliary contacts of the circuit breaker are used to realize electrical interlock. On the basis of controller logic interlock, another layer of electrical interlock is added to realize the dual protection of controller logic interlock and electrical interlock.
Tripping fault: when the circuit breaker overflows tripping, the fault output signal controller detected by the circuit breaker will display the alarm of “switch tripping fault”, and switch from the automatic bit to the manual bit, no longer output the closing command. This function avoids the circuit breaker overcurrent trip, re-closing the damage to the circuit breaker.

In the past two years, we have continuously developed bus controller, three-power ATS controller, dual-power bypass controller and so on. we will continue to make efforts to focus on solutions of complex systems, and develop products such as three-line and one-bus, three-line and two-bus, etc. we will continue to update the products according to your valuable advices and requirements for application use are welcomed to improve our product lines.
