Summary

The content of this proposal report is in response to the project developed in the geographical region of west London where the civil structure of a theater, established in 1919, has been going under renovation in order to maintain its existence from a decade. In doing so the structure has been observed keenly and on the permission and assistance of the working team over there, the idea of proposing a fusion of the modern technology and the ethical design technology of past will give a revolutionary transformation to the theatre. The project proposal will fulfill the needs and requirements of the structural requirements and will provide a permanent solution for their every possible needs.

Introduction

On observing the structure and analyzing it, we came to know that the power system of the structure is of out of the wall or, to be precise, is wall mounted in nature which is prone to many wear and tear conditions in which the temperature variation is an important factor as

In west London, the cold and the humidity levels affects the insulation of the conductors, and thus, the magnetic and electrical properties. Therefore, we would like to propose a new modified method of cable distribution of in wall cable mounting. This not only saves the conductor maintenance and other modifications, but it is also easy to have repairing and other enhancements in the system without having to work out with the whole of the system.

Also for the lighting and the other power requirements we have a proposal of mixed source supply (a combination of conventional and non-conventional resources of energy). the former is distributed into sections of each room structure, and for the large loads, the load distribution is done on the conventional and non-conventional sources (Solar panel system).

For the façade optimization and the other frontal modifications, the power system is designed in such a way that the day time environment inside the structure always remain stable rather than outside environment.

Needs/Problems

On analyzing the structure, we observed that the building is designed in the rectangular perimeter of the lan portion in which the ventilation is done in the unidirectional method. Following is the rough sketch of the actual structure divided into ground floor and first floor respectively.

Fig 1: Ground floor

Fig 2: First Floor

Thus, from the above figures, it is clear that the structure is designed in a very simple way with not much efforts are done in the ventilation circulation divisions. Next, our main concern is the power distribution.

On analyzing the structure, we came observed following facts: –

1. No modular system for power distribution of power in different sections.
2. Single control section for the distribution of power.
3. No ambient lighting or use of natural illuminance in the structure.
4. Wastage of power in application of rusty and carbon coated old connectors
5. Poor power fault protection of the system.
6. No auxiliary power or backup power circuitry system in case of power failure.
7. No protection against thunder and lightning
8. Outdated power cables application
9. Interference in the communication lines
10. Outdated fire protection plan.

Thus, on the basis of above observations we have provided solutions which will increase the life by 80% and reduces the losses by 93 percent.

Procedures/Scope of Work

Based on above identified issues, we came on the conclusion of addressing each problem by using integrated system at modular levels. This means for a single consolidated bunch of systems we will send a bidirectional cable for distribution which will serve many purposes. In the diagram they are represented as follows: –

Fig 4

Also the integrated systems are as follows: –

Fig 5

Fig 6

The above are the systems which are employed in the system for the having multipurpose functionality and also has also have durability under adverse conditions.

For the distribution of power, we have used busbar section having equipotential technology over various load up to 40 amps of connections in various mccb and mcb connections. For the power system we have used some of the following devices: –

Fig 7

Based upon the various loads and the types the ACB, MCB, MCCB are installed in the circuit. Even for the measuring the power in the Busbar system the power meter named as “M2” are installed with each load distribution as shown below: –

Fig 8

Also the non-conventional power system which serves as the power supply source for distribution has generation capacity of 10KW of energy in per hour basis on a bright sunny day. The figure below shows a description of roof top arrangement: –

Fig 9

Also in order to tackle any failure of power and the constrain of disconnection of power, we have employed Auxiliary ring main system which is as shown below: –

Fig 10

As shown in the figure above the aux. ring connection connects one spare of the DB unit with another so that a ring system will be made and the failure of power is efficiently tackled. In order to solve the problem of multiple cables, we have used multi core-cables of standard 4 core,2 core, XLPE core etc.

In the lighting section, the façade optimization is done with the help of the above mentioned integrated system which includes proximity, IR,motion and ambiance sensors which adjust lightings and luminance as per the intensity of lighting from the environment outside. Thus, reducing the electricity bill of theatre by 63.8 percent.

Conclusion

Thus, on employing the above systems and methodologies one, can surely get from the figures of the optimization and the modifications that the use of green technology along with the modular systems of the integrated control units has a better effect and the geometrical position of the systems not only provide the better output, but also a reliable one in the context of the longevity of the application. All the necessary protection such as the lightning arrestor, the protection fuses and the automatic/mechanical isolator provides an add-on protection and also makes the periodical maintenance easy and secure along with noninterference in the communication system such as WiFi, Ethernet and POE systems.

Thus, following are some of the advantages achieved by employing the above systems: –

1. Better and controlled distribution of power
2. Easy maintenance control without shutting down whole system
3. Efficient use of power in lighting systems.
4. Decrease in losses in power in connectors
5. Better power fault protection of the system.
6. Secure and reliable backup power circuitry system in case of power failure.
7. Complete protection against thunder and lightning
8. Minimum power cables losses application leading to simpler wiring system
9. No Interference in the communication lines
10. Complete protection against fire protection and other hazards.
