I. INTRODUCTION
The underground surroundings of the coal mines are very execrable. One side, it is the moist, high dust and inflammable surroundings. On the other side, the space of roadway is limited since it is necessary to save the investment of exploiting coal mines so that it is difficult to maintain the equipments. In the modern coal mines, the automatization equipments could be used widely. The
faults of the automatization equipments could affect the production and the benefit of the coal mines. The shearer is the mining equipment that coal could be cut from the coal wall. The traditional shearer was driven by the hydrostatic transmission system. The fault ratio of the hydrostatic transmission system is high since the fluid in hydrostatic transmission system could be polluted easily. The faults of the hydrostatic transmission system could affect the production and the benefit of the coal mines directly. The fault ratio of the motor drive system is lower than that of the hydrostatic transmission system, but it is difficult to cool the motor drive system in coal mines since the motor drive system should be installed within the flameproof enclosure for safety protection. The motor drive system is also one of the pivotal parts in the automatization equipments. The development of the novel types of the motor drive system had been attached importance to by the coal mines. The Switched Reluctance motor drive could become the main equipments for adjustable speed electrical drive system in coal mines [1], because it has the high operational reliability and the fault tolerant ability [2]. The Switched Reluctance motor drive made up of the double-salient pole Switched Reluctance motor, the unipolar power converter and the controller is firm in the motor and in the power converter. There is no brush structure in the motor and no fault of ambipolar power converter in the power converter [3][4]. The Switched Reluctance motor drive could be operated at the condition of lacked phases fault depended on the independence of each phase in the motor and the power converter [5]. There is no winding in the rotor so that there is no copper loss in the loss and there is only little iron loss in the rotor. It is easy to cool the motor since it is not necessary to cool the rotor. The shearer driven by the Switched Reluctance motor drive had been developed. The paper presented the developed prototype.
II. SYSTEM COMPONENTS
The developed Switched Reluctance motors drive for the electrical traction in shearer is a type of the double Switched Reluctance motors parallel drive system. The system is made up of two Switched Reluctance motors, a control box installed the power converter and the controller. The adopted two Switched Reluctance motors are all three-phase 12/8 structure Switched Reluctance motor, which were shown in Figure 1. The two Switched Reluctance motors were packing by the explosion-proof enclosure, respectively. The rated output power of one motor is 40 KW at the rotor speed 1155 r/min, and the adjustable speed range is from 100 r/min to 1500r/min.
Figure 1.Photograph of the two three-phase 12/8 structure Switched Reluctance motor
The power converter consists of two three-phase asymmetric bridge power converter in parallel. The IGBTs were used as the main switches. Three-phase 380V AC power source was rectificated and supplied to the power converter. The main circuit of the power converter was shown in Figure 2
Figure 2. Main circuit of the power converter
. In the controller, there were the rotor position detection circuit, the commutation circuit, the current and voltage protection circuit, the main switches’ gate driver circuit and the digital controller for rotor speed closed-loop and balancing the distribution of the loads.
III. CONTROL STRATEGY
The two Switched Reluctance motor could all drive the shearer by the transmission outfit in the same traction guide way so that the rotor speed of the two Switched Reluctance motors could be synchronized.
The closed-loop rotor speed control of the double Switched Reluctance motors parallel drive system could be implemented by PI algorithm. In the Switched Reluctance motor 1, the triggered signals of the main switches in the power converter are modulated by PWM signal, the comparison of the given rotor speed and the practical rotor speed are made and the duty ratio of PWM signal are regulated as follows,
where, is the given rotor speed, is the practical rotor speed, is the difference of the rotor speed, is the increment of the duty ratio of PWM signal of the Switched Reluctance motor 1 at k time, is the integral coefficient, is the proportion coefficient, ek is the difference of the rotor speed at k time, ek-1 is the difference of the rotor speed at k-1 time, D1(k) is the duty ratio of PWM signal of the Switched Reluctance motor 1 at k time, and D1(k-1) is the duty ratio of PWM signal of the Switched Reluctance motor 1 at k-1 time. The output power of the Switched Reluctance motor drive system is approximately in proportion to the average DC supplied current of the power converter as follows,
where, P2 is the output power of the Switched Reluctance motor drive system, Iin is the average DC supplied current of the power converter.
In the Switched Reluctance motor 2, the triggered signals of the main switches in the power converter are also modulated by PWM signal. The balancing the distribution of the loads between the two Switched Reluctance motors could be implemented by fuzzy logic algorithm. In the fuzzy logic regulator, there are two input control parameters, one is the deviation of the average DC supplied current of the power converter between the two Switched Reluctance motors, and the other is the variation of the deviation of the average DC supplied current of the power converter between the two Switched Reluctance motors. The output control parameter is the increment of the duty ratio of the PWM signal of the Switched Reluctance motor 2. The block diagram of the double Switched Reluctance motors parallel drive system for the electrical traction in shearer was shown in Figure 3.
Figure 3. Block diagram of the double Switched Reluctance motors parallel drive system for the electrical traction in shearer
The deviation of the average DC supplied current of the power converter between the two Switched Reluctance motors at the moment of ti is
where, Iin1 is the practical average DC supplied current of the power converter in the Switched Reluctance motor 1 at the moment of ti, Iin2 is the practical average DC supplied current of the power converter in the Switched Reluctance motor 2 at the moment of ti.
The variation of the deviation of the average DC supplied current of the power converter between the two Switched Reluctance motors at the moment of ti is
where, ei-1 is the deviation of the average DC supplied current of the power converter between the two Switched Reluctance motors at the moment of ti-1.
The duty ratio of the PWM signal of the Switched Reluctance motor 2 at the moment of ti is
where, ΔD2(i) is the increment of the duty ratio of the PWM signal of the Switched Reluctance motor 2 at the moment of ti and D2(i-1) is the duty ratio of the PWM signal of the Switched Reluctance motor 2 at the moment of ti-1.
The fuzzy logic algorithm could be expressed as follows,
where, E is the fuzzy set of the deviation of the average DC supplied current of the power converter between the two Switched Reluctance motors, EC is the fuzzy set of the variation of the deviation of the average DC supplied current of the power converter between the two Switched Reluctance motors, and U is the fuzzy set of the increment of the duty ratio of the PWM signal of the Switched Reluctance motor 2.
The continuous deviation of the average DC supplied current of the power converter between the two Switched Reluctance motors could be changed into the discrete amount at the interval [-5, +5], based on the equations as follows,
The continuous variation of the deviation of the average DC supplied current of the power converter between the two Switched Reluctance motors could also be changed into the discrete amount at the interval [-5, +5], based on the equations as follows,
The discrete increment of the duty ratio of PWM signal of the Switched Reluctance motor 2 at the interval [-5, +5] could be changed into the continuous amount at the interval [-1.0%, +1.0%], based on the equations as follows,
There is a decision forms of the fuzzy logic algorithm based on the above principles, which was stored in the programme storage cell of the controller.
While the difference of the distribution of the loads between the two Switched Reluctance motors could be got, the duty ratio of PWM signal of the Switched Reluctance motor 2 will be regulated based on the decision forms of the fuzzy logic algorithm and the distribution of the loads between the two Switched Reluctance motors could be balanced.
IV. TESTED RESULTS
The developed double Switched Reluctance motors parallel drive system prototype had been tested experimentally. Table I gives the tests results, where σ is the relative deviation of the average DC supplied current of the power converter in the Switched Reluctance motor 1, σ is the relative deviation of the average DC2 supplied current of the power converter in the Switched
Reluctance motor 2, and,

TESTS RESULTS OF PROTOTYPE
It is shown that the relative deviation of the average DC supplied current of the power converter in the Switched Reluctance motor 1 and in the Switched Reluctance motor 2 is within ±10% .
V. CONCLUSION
The paper presented the double Switched Reluctance motors parallel drive system for the electrical traction in shearer. The novel type of the shearer in coal mines driven by the Switched Reluctance motors drive system contributes to reduce the fault ratio of the shearer, enhance the operational reliability of the shearer and increase the benefit of the coal mines directly. The drive type of the double Switched Reluctance motors parallel drive system could also contribute to enhance the operational reliability compared with the drive type of the single Switched Reluctance motor drive system.

Ⅰ.介紹
煤礦的地下環(huán)境是非常惡劣的。一方面由于它是潮濕的,高粉塵的,和易燃的環(huán)境。另一方面，為了節(jié)約開采成本，巷道空間是有限，以至于設(shè)備很難維護(hù)。自動(dòng)化設(shè)備在現(xiàn)代化煤礦已經(jīng)得到廣泛應(yīng)用。自動(dòng)化設(shè)備的故障會(huì)直接影響到煤礦的產(chǎn)量和效益。采煤機(jī)是采煤的主要礦山設(shè)備。傳統(tǒng)的滾筒采煤機(jī)是通過液壓傳動(dòng)系統(tǒng)傳動(dòng)的。液壓傳動(dòng)系統(tǒng)的故障率很高，因?yàn)橐簤簜鲃?dòng)系統(tǒng)的液體很容易受環(huán)境污染。液壓傳動(dòng)系統(tǒng)的故障直接影響到煤礦的產(chǎn)量和效率。電傳動(dòng)系統(tǒng)比液壓傳動(dòng)系統(tǒng)的故障率低。但是，礦井中電機(jī)傳動(dòng)系統(tǒng)的散熱性差，是因?yàn)闉榱嗣旱V安全，電機(jī)傳動(dòng)系統(tǒng)被封裝在防爆的外殼內(nèi)。電機(jī)傳動(dòng)系統(tǒng)是自動(dòng)化設(shè)備的重要組成部分。電機(jī)傳動(dòng)系統(tǒng)的小說類型的發(fā)展對煤礦很重要。開關(guān)磁阻電動(dòng)機(jī)傳動(dòng)是煤礦調(diào)速傳動(dòng)系統(tǒng)的主要設(shè)備，由于它的高工作可靠性和高容錯(cuò)能力。由雙極點(diǎn)開關(guān)磁阻電動(dòng)機(jī)，單級功率變換器和控制器組成的開關(guān)磁阻電動(dòng)機(jī)傳動(dòng)是電動(dòng)機(jī)和功率變換器的核心。電動(dòng)機(jī)沒有毛刷，功率變換器沒有雙極功率變換器的故障。開關(guān)磁阻電動(dòng)機(jī)傳動(dòng)可以在缺相的情況下運(yùn)行，它是依靠電動(dòng)機(jī)和功率變換器相位獨(dú)立性來實(shí)現(xiàn)的。轉(zhuǎn)子上沒有繞組，以至于轉(zhuǎn)子上沒有銅損和很小的鐵損。因?yàn)椴恍枰鋮s轉(zhuǎn)子，所以很容易冷卻電動(dòng)機(jī)。由開關(guān)磁阻電動(dòng)機(jī)傳動(dòng)的采煤機(jī)正在不斷發(fā)展。本章介紹了發(fā)展的樣機(jī)。
